Definitions

  • the present invention relates to a decorative piece.
  • This decorative piece comprises a support in which at least one aesthetic element is crimped.
  • the support is made of metal alloy and is machined for housing to appear. During this machining, fastening means in the form of hooks are made. Generally, these hooks are made with the material forming the portable object that is to say one-piece with the object.
  • an aesthetic element such as a gemstone
  • the latter is placed in a housing and the attachment means are folded cold by plastic deformation so as to maintain said aesthetic element in the housing.
  • This method of crimping is widely used to crimp precious stones on metal supports because the latter has an advantageous plastic deformation capacity. This ability is even more advantageous with precious metals such as gold because these precious metals are ductile and can be easily shaped.

  • alloys having relatively low elastic limits are generally chosen to facilitate the work of the crimper.
  • it is necessary that the alloy has sufficient elongation before rupture to be able to fold the attachment means without breaking.
  • this elongation is the consequence of both the elements present in the alloy and the thermomechanical history of the latter.
  • the gold alloys used in watchmaking have an elastic limit of the order of 200-400 MPa and an elongation at break of 20-40%.
  • Type 1.4435 stainless steels have a yield strength of 200-300 MPa and an elongation at break of 25-45%.
  • a disadvantage of this method is that it is confined to supports made of ductile metals or metal alloys.
  • more and more timepieces are made in materials that do not exhibit plastic deformation, often hard and / or fragile, such as for example ceramic, silicon, composites or intermetallic alloys.
  • Bonding has the disadvantage of not ensuring a 100% stone resistance because unlike crimping, this technique does not involve mechanical retention of stones. Indeed, the glued areas being in most cases exposed to the external environment (moisture, sweat, UV, air pollution, ...), the holding of the bonding in the long term is made difficult. Therefore, the holding of the stones is not assured which is not acceptable for quality products.

Conversely, when the inclination generates a larger section at the surface of the support 2, maintaining the material amorphous in the hollow 4 is no longer optimal.

Description

La présente invention concerne une pièce décorative. Cette pièce décorative comprend un support dans lequel au moins un élément esthétique est serti.The present invention relates to a decorative piece. This decorative piece comprises a support in which at least one aesthetic element is crimped.

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

Il est connu dans l'art antérieur des pièces décoratives destinées à être rapportées sur un objet portable tel une montre ou un bijou et consistant au sertissage d'élément esthétique sur les parties dudit objet portable faisant office de support.It is known in the prior art decorative pieces intended to be reported on a portable object such as a watch or a jewel and consisting in the crimping of aesthetic element on the parts of said portable object acting as a support.

Pour cela, le support est réalisé en alliage métallique et est usiné pour que des logements apparaissent. Lors de cet usinage, des moyens d'accroche se présentant sous la forme de crochets, sont réalisés. Généralement, ces crochets sont réalisés avec la matière formant l'objet portable c'est-à-dire de façon monobloc avec l'objet. Lorsqu'un élément esthétique, telle une pierre précieuse, doit être serti, ce dernier est placé dans un logement et les moyens d'accroche sont rabattus à froid par déformation plastique de sorte à maintenir ledit élément esthétique dans le logement. Cette méthode de sertissage est largement répandue pour sertir des pierres précieuses sur des supports en métal car ce dernier présente une capacité de déformation plastique avantageuse. Cette capacité est encore plus avantageuse avec des métaux précieux comme l'or, car ces métaux précieux sont ductiles et peuvent être facilement façonnés. La déformation plastique à froid des métaux cristallins est possible grâce aux mouvements des dislocations présentes dans les réseaux cristallins. La limite élastique, c'est-à-dire la contrainte au-delà de laquelle un matériau commence à se déformer plastiquement, d'un alliage cristallin dépend des éléments composant ce dernier ainsi que de l'historique thermo-mécanique de l'alliage. Pour le sertissage traditionnel, des alliages ayant des limites élastiques relativement faibles sont généralement choisis afin de faciliter le travail du sertisseur. En plus d'une limite élastique relativement faible, il est nécessaire que l'alliage présente un allongement avant rupture suffisant afin de pouvoir rabattre les moyens d'accroche sans qu'ils cassent. Tout comme pour la limite élastique, cet allongement est la conséquence à la fois des éléments présents dans l'alliage et de l'histoire thermo-mécanique de ce dernier. Par exemple, les alliages d'or utilisés dans l'horlogerie ont une limite élastique de l'ordre de 200-400MPa et un allongement à la rupture de 20-40%. Les aciers inoxydables de type 1.4435 ont une limite élastique de 200-300 MPa et un allongement à la rupture de 25-45%.For this, the support is made of metal alloy and is machined for housing to appear. During this machining, fastening means in the form of hooks are made. Generally, these hooks are made with the material forming the portable object that is to say one-piece with the object. When an aesthetic element, such as a gemstone, is to be crimped, the latter is placed in a housing and the attachment means are folded cold by plastic deformation so as to maintain said aesthetic element in the housing. This method of crimping is widely used to crimp precious stones on metal supports because the latter has an advantageous plastic deformation capacity. This ability is even more advantageous with precious metals such as gold because these precious metals are ductile and can be easily shaped. The cold plastic deformation of the crystalline metals is possible thanks to the movements of the dislocations present in the crystalline lattices. The elastic limit, that is to say the stress beyond which a material begins to deform plastically, of a crystalline alloy depends on components of the latter as well as the thermomechanical history of the alloy. For traditional crimping, alloys having relatively low elastic limits are generally chosen to facilitate the work of the crimper. In addition to a relatively low elastic limit, it is necessary that the alloy has sufficient elongation before rupture to be able to fold the attachment means without breaking. As for the elastic limit, this elongation is the consequence of both the elements present in the alloy and the thermomechanical history of the latter. For example, the gold alloys used in watchmaking have an elastic limit of the order of 200-400 MPa and an elongation at break of 20-40%. Type 1.4435 stainless steels have a yield strength of 200-300 MPa and an elongation at break of 25-45%.

Néanmoins, un inconvénient de cette méthode est qu'elle est cantonnée aux supports réalisés en métaux ou alliages métalliques ductiles. Or, de plus en plus de pièces d'horlogerie sont réalisées dans des matériaux ne présentant pas de déformation plastique, souvent durs et/ou fragiles, comme par exemple la céramique, le silicium, les composites ou encore des alliages intermétalliques.Nevertheless, a disadvantage of this method is that it is confined to supports made of ductile metals or metal alloys. However, more and more timepieces are made in materials that do not exhibit plastic deformation, often hard and / or fragile, such as for example ceramic, silicon, composites or intermetallic alloys.

De ce fait, il n'est plus possible d'utiliser la méthode actuelle pour sertir des éléments esthétiques comme par exemple des pierres précieuses.Therefore, it is no longer possible to use the current method to crimp aesthetic elements such as precious stones.

Cette opération de sertissage est donc remplacée par une opération de collage. Le collage a pour désavantage de ne pas assurer une tenue des pierres à 100% car contrairement au sertissage, cette technique n'implique pas une retenue mécanique des pierres. En effet, les zones collées étant dans la majorité des cas exposées à l'environnement extérieur (humidité, sueur, UV, pollution de l'air,...), la tenue du collage sur le long terme est rendue difficile. Par conséquent, la tenue des pierres n'est pas assurée ce qui n'est pas acceptable pour des produits de qualité.This crimping operation is therefore replaced by a gluing operation. Bonding has the disadvantage of not ensuring a 100% stone resistance because unlike crimping, this technique does not involve mechanical retention of stones. Indeed, the glued areas being in most cases exposed to the external environment (moisture, sweat, UV, air pollution, ...), the holding of the bonding in the long term is made difficult. Therefore, the holding of the stones is not assured which is not acceptable for quality products.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Dans la description suivante, toutes les parties de la pièce décorative qui sont bien connues de l'homme du métier dans ce domaine technique ne seront expliquées que de manière simplifiée.In the following description, all parts of the decorative part which are well known to those skilled in this technical field will be explained in a simplified manner.

Comme visible aux figures 1 et 2, la présente invention est une pièce décorative 1. Elle se compose d'une première partie 2 et d'une seconde partie 3. Les deux parties 2, 3 sont agencées pour se solidariser l'une à l'autre. Plus particulièrement, la seconde partie 3 est destinée à être sertie dans la première partie 2. Par exemple, la première partie peut être un support 2 et, la seconde 3, un ou plusieurs éléments esthétiques. Ce ou ces éléments esthétiques 3 peuvent être des pierres précieuses comme des diamants ou rubis ou non précieuses comme des zircons ou tout autre élément esthétique possible.As visible to Figures 1 and 2 the present invention is a decorative piece 1. It consists of a first part 2 and a second part 3. The two parts 2, 3 are arranged to become integral with each other. More particularly, the second part 3 is intended to be crimped in the first part 2. For example, the first part may be a support 2 and the second part 3, one or more aesthetic elements. This or these aesthetic elements 3 can be precious stones such as diamonds or rubies or non precious like zircons or any other possible aesthetic element.

Sur les figures 1 et 2 sont représentés des exemples de réalisation de l'invention. La pièce décorative 1 peut être, par exemple, une lunette de montre 10 incrustée d'indices comme visible à la figure 1 ou une glace de montre 11 visible à la figure 2 ou un cadran 22 ou toute parties extérieures d'une montre ou pièce d'horlogerie. Dans l'exemple d'un cadran, ce dernier comporte un corps discoïdal formant le support 2 dans lequel sont sertis des éléments esthétiques 3. Ce cadran peut être, par exemple, réalisé en céramique. On comprendra que la céramique n'est pas le seul matériau à pouvoir être utilisé. Ainsi, tout matériau ne présentant pas de déformation plastique suffisante peut être utilisé tel que le saphir, le silicium ou le verre. Dans le cas d'une glace en saphir, l'intérêt est de sertir ladite glace permettant un effet visuel en trois dimensions comme un tour d'heure ou un logo au-dessus des aiguilles. On comprendra que la pièce décorative 1 peut être également un stylo ou un bouton de manchette ou un article de bijouterie comme une bague ou une boucle d'oreille. La surface du support 2 qui sera sertie peut être plane ou courbe c'est-à-dire concave ou convexe.On the Figures 1 and 2 exemplary embodiments of the invention are shown. The decorative piece 1 may be, for example, a watch bezel 10 inlaid with indicia as visible in FIG. figure 1 or a watch glass 11 visible to the figure 2 or a dial 22 or any external parts of a watch or timepiece. In the example of a dial, the latter comprises a discoidal body forming the support 2 in which are crimped aesthetic elements 3. This dial can be, for example, made of ceramic. It will be understood that ceramics are not the only material that can be used. Thus, any material that does not exhibit sufficient plastic deformation can be used such as sapphire, silicon or glass. In the case of a sapphire crystal, the interest is to crimp the said ice allowing a visual effect in three dimensions such as a time lapse or a logo above the needles. It will be understood that the decorative piece 1 can also be a pen or a cufflink or a jewelery item such as a ring or an earring. The surface of the support 2 which will be crimped may be flat or curved, that is to say concave or convex.

Avantageusement selon l'invention, ce support 2 comporte au moins une creusure 4, représentée sur la figure 4, aménagée sur ledit support pour permettre le sertissage d'au moins un élément esthétique. Chaque creusure 4 se présente alors sous la forme d'un motif et possède des flancs 7, de préférence sensiblement perpendiculaires à la surface visible. Ces creusures 4 sont utilisées pour permettre l'utilisation d'un substrat 6 pour le sertissage. En effet, l'invention se propose de remplir ladite creusure 4 avec un premier matériau plus facilement déformable de sorte à pouvoir sertir ledit au moins un élément esthétique 3, ce qui n'est pas possible avec un support 2 en céramique ou silicium. Ainsi pour remplir lesdites creusures 4, il est envisagé d'utiliser dans la présente invention un premier matériau métallique.Advantageously according to the invention, this support 2 comprises at least one recess 4, represented on the figure 4 , arranged on said support to allow the crimping of at least one aesthetic element. Each recess 4 is then in the form of a pattern and has flanks 7, preferably substantially perpendicular to the visible surface. These recesses 4 are used to allow the use of a substrate 6 for crimping. Indeed, the invention proposes to fill said hollow 4 with a first material more easily deformable so as to crimp said at least one aesthetic element 3, which is not possible with a support 2 of ceramic or silicon. Thus to fill said recesses 4, it is envisaged to use in the present invention a first metal material.

La première étape, visible à la figure 3, consiste à se munir du support 2 dans un matériau qui ne se déforme pas plastiquement.The first step, visible at figure 3 is to provide the support 2 in a material that does not deform plastically.

La seconde étape, visible à la figure 4, consiste donc à réaliser au moins une creusure 4 dans le support 2. Cette creusure 4 peut être réalisée par exemple par usinage, par ablation laser, voir directement lors du moulage du support ou par toute autre technique.The second step, visible at figure 4 , This consists of making at least one recess 4 in the support 2. This recess 4 can be made for example by machining, by laser ablation, see directly during the molding of the support or by any other technique.

La troisième étape consiste à remplir ladite creusure avec un premier matériau. Ce premier matériau est alors utilisé pour servir de substrat 6. La troisième étape permet d'obtenir le support 2 visible à la figure 6.The third step is to fill said recess with a first material. This first material is then used to serve as a substrate 6. The third step makes it possible to obtain the support 2 visible at the figure 6 .

Avantageusement selon l'invention, le premier matériau est un alliage métallique amorphe. On comprendra également que le matériau métallique sera partiellement amorphe ou totalement amorphe. Le terme partiellement amorphe indique que pour un bloc de matière, le pourcentage de quantité de matière dudit bloc présentant l'état amorphe est suffisant pour que le bloc en lui-même présente les caractéristiques spécifiques aux métaux et alliages métalliques amorphes. Les matériaux amorphes ont l'avantage de pouvoir être facilement mis en forme. De même, il peut être possible d'utiliser un métal précieux ou un de ces alliages afin de donner un caractère noble à ladite pièce décorative. Ainsi, le métal précieux ou un de ces alliages est compris dans la liste comportant l'or, le platine, le palladium, le rhénium, le ruthénium, le rhodium, l'argent, l'iridium ou l'osmium.Advantageously according to the invention, the first material is an amorphous metal alloy. It will also be understood that the metallic material will be partially amorphous or totally amorphous. The partially amorphous term indicates that for a block of material, the percentage of material amount of said block having the amorphous state is sufficient for the block itself to have the characteristics specific to amorphous metals and metal alloys. The amorphous materials have the advantage of being easily shaped. Similarly, it may be possible to use a precious metal or one of these alloys to give a noble character to said decorative piece. So, the precious metal or one of these alloys are included in the list comprising gold, platinum, palladium, rhenium, ruthenium, rhodium, silver, iridium or osmium.

Une des méthodes pour remplir la creusure consiste à utiliser le formage à chaud. Les figures 5 et 6 représentent de manière simplifiée les étapes de remplissage de la creusure 4. Au préalable, il est, d'une part, nécessaire de réaliser le support 2 comme visible à la figure 3 et, d'autre part, de réaliser une préforme 6a en alliage métallique amorphe. Cette préforme 6a peut être réalisée par différentes techniques telles que par exemple l'injection dans un moule de forme, le formage à chaud au-dessus de Tg, l'étampage de bande, ou encore par usinage. Une fois cette préforme 6a réalisée, elle est placée au-dessus du support 2, comme visible à la figure 5, sur la face où débouche lesdites creusures 4 pour réaliser le remplissage desdites creusures par formage à chaud. L'ensemble est alors chauffé à une température supérieure à la température de transition vitreuse Tg , permettant ainsi une diminution de la viscosité de la préforme, puis une pression est exercée. Une fois ces conditions réunies, la pression exercée sur la préforme visqueuse permet à l'alliage métallique amorphe visqueux de remplir la creusure 4 comme visible à la figure 6. Ensuite, lorsque les creusures 4 sont remplies comme visible à la figure 6, on refroidit l'ensemble afin de conserver l'état amorphe de l'alliage.One of the methods to fill the hollow is to use hot forming. The Figures 5 and 6 represent in a simplified manner the steps of filling the hollow 4. In the first place, it is necessary, on the one hand, to make the support 2 visible to the figure 3 and, on the other hand, to produce a preform 6a of amorphous metal alloy. This preform 6a may be made by various techniques such as, for example, injection into a form mold, hot forming above Tg, stamping of the strip, or by machining. Once this preform 6 has been made, it is placed above the support 2, as visible in FIG. figure 5 on the face where said digs 4 open to perform the filling of said recesses by hot forming. The assembly is then heated to a temperature above the glass transition temperature Tg, thus allowing a decrease in the viscosity of the preform, and then a pressure is exerted. Once these conditions are met, the pressure exerted on the viscous preform allows the viscous amorphous metal alloy to fill the recess 4 as visible in FIG. figure 6 . Then, when the recesses 4 are filled as visible in the figure 6 the whole is cooled in order to maintain the amorphous state of the alloy.

Ce type de matériaux convient bien du fait qu'ils peuvent ainsi facilement remplir tout le volume de la creusure 4. Après refroidissement, les flancs 7 verticaux permettent de retenir le matériau amorphe par frottements. Bien entendu, les flancs 7 peuvent être inclinés de façon à rétrécir la surface du plan horizontal au fond de la creusure 4 ou bien au contraire de sorte à l'agrandir. Il va de soi que le cas le plus avantageux est celui où la surface du fond de la creusure 4 est la plus grande puisqu'elle permet de retenir naturellement l'alliage métallique amorphe dans la creusure 4. Inversement, lorsque l'inclinaison engendre une section plus grande au niveau de la surface du support 2, le maintien du matériau amorphe dans la creusure 4 n'est plus optimal. Un autre avantage est que cette viscosité qui diminue entraîne une diminution de la contrainte à appliquer pour remplir les creusures 4 avec l'alliage métallique amorphe. De ce fait, le support 2 en matériaux fragiles ne risque pas de se briser bien qu'une opération de pressage soit effectuée.This type of material is well suited to the fact that they can easily fill the entire volume of the hollow 4. After cooling, the vertical flanks 7 can retain the amorphous material by friction. Of course, the flanks 7 may be inclined to shrink the surface of the horizontal plane at the bottom of the recess 4 or on the contrary so as to enlarge. It goes without saying that the most advantageous case is that where the surface of the bottom of the hollow 4 is the largest since it allows to naturally retain the amorphous metal alloy in the recess 4. Conversely, when the inclination generates a larger section at the surface of the support 2, maintaining the material amorphous in the hollow 4 is no longer optimal. Another advantage is that this decreasing viscosity causes a decrease in the stress to be applied to fill the recesses 4 with the amorphous metal alloy. Therefore, the support 2 of fragile materials is not likely to break although a pressing operation is performed.

Bien entendu, d'autres types de mise en forme sont possibles comme la mise en forme par coulée ou injection, par densification de poudre ou par chassage.Of course, other types of formatting are possible such as shaping by casting or injection, by densification of powder or by driving.

Le procédé de coulée ou injection consiste à chauffer une préforme métallique au-dessus de son point de fusion et puis à couler ou injecter le métal liquide ainsi obtenu dans la creusure 4 du support 2.The casting or injection process consists of heating a metal preform above its melting point and then pouring or injecting the liquid metal thus obtained into the hollow 4 of the support 2.

Le procédé de densification de poudre consiste à introduire une poudre métallique dans la creusure 4 du support 2 et à la consolider par un apport d'énergie tel un four, un faisceau laser, un faisceau ionique ou tout autre moyen thermique. Une fois la creusure 4 remplie, une étape de refroidissement jusqu'à une température inférieure à Tg est effectuée afin d'éviter la cristallisation de l'alliage pour obtenir une creusure 4 remplie d'alliage métallique amorphe ou semi-amorphe.The powder densification process consists in introducing a metal powder into the hollow 4 of the support 2 and consolidating it by a supply of energy such as an oven, a laser beam, an ion beam or any other thermal means. Once the hollow 4 filled, a cooling step to a temperature below Tg is performed to prevent the crystallization of the alloy to obtain a hollow 4 filled with amorphous or semi-amorphous metal alloy.

Le procédé de chassage consiste à réaliser un bloc d'alliage métallique amorphe dont les dimensions et la forme sont légèrement plus grandes que celles de la creusure 4 et à forcer ce bloc à rentrer dans ladite creusure 4. Avantageusement, il peut être prévu de réaliser cette étape d'assemblage en utilisant la dilatation thermique. Pour se faire, le support 2 est chauffé de sorte que, sous l'effet de la chaleur, il se dilate thermiquement. Le support 2 voit ses dimensions augmentées. Cette augmentation des dimensions est également applicable à la creusure 4. Par conséquent la différence entre les dimensions de la creusure 4 et les dimensions du bloc est modifiée de sorte que les dimensions de la creusure 4 deviennent plus importantes que celles du bloc. Il est alors aisé d'insérer le bloc dans la creusure 4. Lorsque le support 2 est refroidit, il reprend ses dimensions initiales et le bloc se retrouve coincé dans ladite creusure 4.The hunting method consists in producing an amorphous metal alloy block whose dimensions and shape are slightly larger than those of the recess 4 and forcing this block to enter said recess 4. Advantageously, it can be provided to realize this assembly step using thermal expansion. To do this, the support 2 is heated so that, under the effect of heat, it is thermally expanded. The support 2 sees its dimensions increased. This increase in dimensions is also applicable to the recess 4. Consequently, the difference between the dimensions of the recess 4 and the dimensions of the block is modified so that the dimensions of the recess 4 become larger than those of the block. It is then easy to insert the block in the hollow 4. When the support 2 is cooled, it resumes its initial dimensions and the block is stuck in said hollow 4.

Une fois la creusure remplie, une quatrième étape de préparation est effectuée. Cette étape consiste à fabriquer les logements (trous) 8 de sertissage dans lequel les éléments esthétiques 3 sont placés, et à fabriquer les moyens d'accroches. Cette étape peut être réalisée soit de manière classique tels que l'usinage, le fraisage, le perçage, soit de manière moins classique, par déformation à chaud, soit par un mixte des deux manières. La méthode de déformation à chaud consiste à utiliser un outil ayant la géométrie négative du trou et de l'élément de sertissage et à appliquer cet outil, avec une certaine force et à une température supérieure à la température de transition vitreusee Tg du métal amorphe, sur l'alliage métallique amorphe remplissant la creusure 4. Il est ainsi possible d'éviter les étapes d'usinage qui peuvent être difficiles selon les alliages métalliques amorphes utilisés.Once the hollow is filled, a fourth preparation step is performed. This step consists of manufacturing the crimping housings (holes) 8 in which the aesthetic elements 3 are placed, and to manufacture the hooking means. This step can be carried out either conventionally such as machining, milling, drilling, or in a less conventional manner, by hot deformation, or by a combination of both ways. The method of hot deformation comprises using a tool having the negative geometry of the hole and the crimping element and applying this tool, with a certain force and at a temperature higher than the glass transition temperature Tg of the amorphous metal, on the amorphous metal alloy filling the hollow 4. It is thus possible to avoid the machining steps that can be difficult depending on the amorphous metal alloys used.

Les moyens d'accroche 5 se présentant sous la forme d'au moins un élément de sertissage 9. Cet élément de sertissage 9, dans le cas par exemple d'un sertissage grains, consiste en des plots ou grains agencés sur le pourtour de chaque trou de sertissage 8. Ces plots 9, visibles aux figures 8 et 10, sont réalisés par usinage et sont réalisés avant ou après le perçage des trous de sertissage 8. En effet, lors de l'usinage des trous, de la matière du substrat 6, c'est à dire du premier matériau, est enlevée de sorte à former ces grains de sertissage 9. De préférence, dans le cas d'un sertissage grain, il est prévu d'avoir idéalement quatre grains de sertissage 9 à proximité de chaque trou de sertissage 8 comme visible à la figure 10.The attachment means 5 is in the form of at least one crimping element 9. This crimping element 9, in the case for example of a grain crimping, consists of studs or grains arranged around the periphery of each crimping hole 8. These studs 9, visible at figures 8 and 10 are made by machining and are made before or after the drilling of the crimping holes 8. In fact, during the machining of the holes, the material of the substrate 6, that is to say of the first material, is removed so to form these crimping grains 9. Preferably, in the case of a crimping grain, it is expected to ideally have four crimping grains 9 near each crimping hole 8 as visible in FIG. figure 10 .

On comprendra que d'autres types de sertissage peuvent être envisagés. Dès lors, le sertissage clos, le sertissage baguette, le sertissage rail ou sertissage invisible sont envisageables. Par exemple, le sertissage clos consiste en un unique élément de sertissage 9 s'étendant sur la périphérie de l'élément esthétique 3. Le sertissage baguette est utilisé pour sertir les éléments esthétiques 3 taillés en baguette. Ce sertissage consiste à prévoir des éléments de sertissage 9 s'étendant parallèlement à chaque côté de l'élément esthétique 3 venant se rabattre sur ce dernier. Pour le sertissage invisible, il est prévu que les éléments de sertissage 9 soient des portions saillantes agencées dans le trou de sertissage 8. Ces portions saillantes coopèrent avec au moins une gorge réalisées sur ledit élément esthétique 3 de sorte que le sertissage se fait en insérant l'élément esthétique 3 dans le trou 8 jusqu'à ce que les portions saillantes s'insèrent dans ladite au moins une gorge.It will be understood that other types of crimping can be envisaged. Therefore, closed crimping, crimping stick, crimping rail or invisible crimping are possible. For example, the closed crimping consists of a single crimping element 9 extending on the periphery of the aesthetic element 3. The crimping rod is used to crimp the aesthetic elements 3 cut into baguette. This crimping consists in providing crimping elements 9 extending parallel to each side of the aesthetic element 3 coming down on the latter. For invisible crimping, it is provided that the crimping elements 9 are projecting portions arranged in the crimping hole 8. These projecting portions cooperate with at least one groove made on said aesthetic element 3 so that the crimping is done by inserting the aesthetic element 3 in the hole 8 until the projecting portions fit into said at least one groove.

Dans un exemple particulier de réalisation visible à la figure 10, l'élément esthétique 3 se présente sous la forme d'un diamant comprenant une culasse 3b dans laquelle sont taillées plusieurs facettes et une couronne 3c également facettée surmontée d'une table 3d comme visible à la figure 15. Cet élément esthétique présente, vue de dessus, une forme sensiblement circulaire. Pour que l'illusion d'un sertissage dans le matériau du support 2 soit intacte, il est prévu que la largeur de la creusure 4 soit idéalement égale à celle de l'élément esthétique 3. Préférentiellement, on comprendra que la distance entre l'élément esthétique 3 et le bord de la creusure 4 doit être au minimum de 0.01 mm de sorte que l'effet visuel de l'élément esthétique 3 dans le support 2 soit optimal c'est-à-dire d'avoir l'impression que l'élément esthétique 3 reste noyé dans le support 2 en céramique et non dans un métal. Pour la distance maximale entre l'élément esthétique 3 et le bord de la creusure 4, cela dépendra des dimensions et formes des éléments esthétiques 3. A titre d'exemple, pour un élément esthétique 3 d'un diamètre de 1 mm, la distance entre l'élément esthétique 3 et le bord de la creusure 4 sera de 0.45 mm.In a particular example of embodiment visible in the figure 10 , the aesthetic element 3 is in the form of a diamond comprising a yoke 3b in which are cut several facets and a crown 3c also faceted surmounted by a 3d table as visible in the figure 15 . This aesthetic element has, seen from above, a substantially circular shape. For the illusion of crimping in the material of the support 2 is intact, it is expected that the width of the recess 4 is ideally equal to that of the aesthetic element 3. Preferably, it will be understood that the distance between the aesthetic element 3 and the edge of the recess 4 must be at least 0.01 mm so that the visual effect of the aesthetic element 3 in the support 2 is optimal, that is to say to have the impression that the aesthetic element 3 remains embedded in the ceramic support 2 and not in a metal. For the maximum distance between the aesthetic element 3 and the edge of the recess 4, this will depend on the dimensions and shapes of the aesthetic elements 3. For example, for an aesthetic element 3 with a diameter of 1 mm, the distance between the aesthetic element 3 and the edge of the recess 4 will be 0.45 mm.

Dans un autre exemple, on définit que la distance entre l'élément esthétique 3 et le bord de la creusure 4 se compose d'une zone dite travaillée c'est-à-dire une zone dans laquelle les grains de sertissage sont réalisés, cette zone pouvant être creuse, et d'une zone dite non-travaillée qui est une zone esthétique et visuelle. Dans ce cas, cette zone non travaillée sera au minimum de 0.01 mm et au maximum de 0.20mm. De préférence, elle sera de 0.10 mm.In another example, it is defined that the distance between the aesthetic element 3 and the edge of the recess 4 is composed of a so-called worked area, that is to say an area in which the crimping grains are made, this hollow zone, and a so-called non-worked zone which is an aesthetic and visual zone. In this case, this non worked will be at least 0.01 mm and at most 0.20mm. Preferably, it will be 0.10 mm.

De même, on comprendra que la hauteur du trou 8 est au moins égale à la hauteur de la culasse de l'élément esthétique 3. Cela permet, lorsque l'élément esthétique 3 est serti, de voir le moins possible le premier matériau constitutif du substrat 6. Dans ce cas, les grains de sertissage 9, au nombre de quatre, sont réalisés de sorte à présenter une forme de triangle rectangle dont l'hypoténuse est convexe. De préférence, la forme convexe de l'hypoténuse est similaire à la courbure à celle de l'élément esthétique 3 lorsque celui-ci est vu de haut.Similarly, it will be understood that the height of the hole 8 is at least equal to the height of the yoke of the aesthetic element 3. This allows, when the aesthetic element 3 is crimped, to see as little as possible the first material constituting the In this case, the crimping grains 9, four in number, are made so as to have a shape of a right triangle whose hypotenuse is convex. Preferably, the convex shape of the hypotenuse is similar to the curvature to that of the aesthetic element 3 when it is seen from above.

Une fois la quatrième étape de préparation terminée, on obtient le support 2 visible à la figure 7, la cinquième étape de sertissage peut alors avoir lieu.Once the fourth stage of preparation is completed, we obtain the support 2 visible to the figure 7 the fifth crimping step can then take place.

L'étape de sertissage classique consiste en une déformation. Cette technique consiste à poser l'élément esthétique 3 dans le trou 8 et à déformer le substrat et/ou les éléments de sertissage 5 pour les plaquer sur ledit élément esthétique 3 comme visibles aux figures 9 à 13. De ce fait, ce dernier est maintenu dans le trou de sertissage 8. La déformation peut être plastique. Dans ce cas, elle se fait avec un outil appelé perloir 100 utilisé pour déformer chaque élément de sertissage 9, elle permet d'obtenir l'élément esthétique 3 serti de la figure 13.The conventional crimping step consists of deformation. This technique consists in placing the aesthetic element 3 in the hole 8 and in deforming the substrate and / or the crimping elements 5 to press them on said aesthetic element 3 as visible to the Figures 9 to 13 . As a result, the latter is held in the crimping hole 8. The deformation can be plastic. In this case, it is done with a tool called perloir 100 used to deform each crimping element 9, it allows to obtain the aesthetic element 3 set with the figure 13 .

La déformation peut également être élastique ou obtenue par dilatation thermique. Dans le cas de la déformation élastique, le sertissage est obtenu par clipsage de l'élément esthétique dans les moyens d'accroche 5. Il est évident que dans ce cas, une légère déformation plastique des moyens d'accroche 5 pourrait avoir lieu. Dans le cas de la déformation par dilatation thermique, le sertissage est obtenu en chauffant le support 2 à une température suffisamment élevée pour permettre l'incrustation de l'élément esthétique 3 dans son trou 8 sans effort. Le refroidissement permettra ensuite de contracter la matière permettant ainsi de maintenir l'élément esthétique 3 par les moyens d'accroche 5.The deformation may also be elastic or obtained by thermal expansion. In the case of elastic deformation, the crimping is obtained by clipping the aesthetic element in the attachment means 5. It is obvious that in this case, a slight plastic deformation of the attachment means 5 could take place. In the case of deformation by thermal expansion, the crimping is obtained by heating the support 2 to a sufficiently high temperature to allow the encrustation of the aesthetic element 3 in its hole 8 without effort. The cooling will then make it possible to contract the material thus making it possible to maintain the aesthetic element 3 by the attachment means 5.

Il est à noter que les métaux amorphes, contrairement aux métaux cristallins n'ont pas de dislocations et ne peuvent donc pas se déformer plastiquement par le mouvement de ces dernières. Ils ont donc généralement un comportement fragile, c'est-à-dire qu'ils cassent de manière soudaine une fois la limite élastique dépassée. Il a toutefois été constaté que certains alliages amorphes peuvent accommoder une déformation permanente macroscopique par génération de bandes de glissement à l'échelle microscopique. La nature exacte de ces dernières n'est pour l'instant pas clairement identifiée. En plus de dépendre du type d'alliage amorphe, la capacité d'accommoder une déformation permanente dans les métaux amorphes dépend fortement des dimensions de la pièce. Ainsi plus les dimensions de la zone sollicitée sont faibles, plus la déformation permanente pourra être grande. Par exemple, il est possible de plier de manière permanente une bande d'épaisseur 100µm en alliage Pt57.5Cu14.7Ni5.3P22.5 amorphe jusqu'à un angle supérieur à 90° sans rupture, alors qu'une bande de même dimension en alliage Fe56Co7Ni7Zr8Ta8B20 amorphe n'accommodera aucune déformation permanente.It should be noted that amorphous metals, unlike crystalline metals, have no dislocations and can not plastically deform by the movement of the latter. They therefore generally have a fragile behavior, that is to say that they suddenly break once the elastic limit exceeded. It has been found, however, that some amorphous alloys can accommodate macroscopic permanent deformation by generation of slip bands at the microscopic scale. The exact nature of these is not yet clearly identified. In addition to being dependent on the type of amorphous alloy, the ability to accommodate permanent deformation in amorphous metals is highly dependent on the dimensions of the part. Thus, the smaller the dimensions of the area requested, the greater the permanent deformation. For example, it is possible to permanently bend a 100 μm thick strip of amorphous Pt57.5Cu14.7Ni5.3P22.5 alloy to an angle greater than 90 ° without breaking, while a strip of the same dimension in diameter amorphous Fe56Co7Ni7Zr8Ta8B20 alloy will not accommodate any permanent deformation.

Au vu de ce qui précède et pour pouvoir utiliser différents alliages amorphes indépendamment de leur capacité de déformation permanente, différents modes de réalisation ont été imaginés.In view of the above and to be able to use different amorphous alloys independently of their permanent deformation capacity, different embodiments have been devised.

Un premier mode de réalisation est utilisé dans le cas où les alliages amorphes accommodent la déformation permanente et ayant des limites élastiques pas trop élevées, typiquement inférieures à 1500 MPa : La méthode de sertissage est identique à celle utilisée pour les métaux cristallins, c'est-à-dire la déformation plastique à froid des grains 9 créés dans l'alliage amorphe.A first embodiment is used in the case where the amorphous alloys accommodate the permanent deformation and have not too high elastic limits, typically less than 1500 MPa: The crimping method is identical to that used for crystalline metals, it is that is, the cold plastic deformation of the grains 9 created in the amorphous alloy.

Un second mode de réalisation est utilisé dans le cas où les alliages amorphes ayant des limites élastiques trop élevées pour une déformation plastique à froid, typiquement supérieures à 1500 MPa: La méthode de sertissage consiste à chauffer les grains 9 à une température supérieure à la température de transition vitreuse Tg de l'alliage métallique amorphe afin de diminuer fortement la viscosité et donc la force nécessaire à leur déformation. Une fois les grains 9 à la bonne température, ils sont déformés pour que le sertissage puisse avoir lieu. Une opération de refroidissement est ensuite effectuée pour les solidifier et permettre de rendre le sertissage définitif. Cette solution a l'avantage de permettre un contact intime entre l'alliage métallique amorphe et l'élément esthétique 3 ce qui améliore la tenue de ce dernier. En effet, dans le cas de la déformation plastique à froid, autant pour les métaux cristallins qu'amorphes, un retour élastique s'opère lors du relâchement de la force appliquée sur le grain 9. Ce retour implique inévitablement un léger décollement entre le grain 9 et l'élément esthétique 3, ce qui peut engendrer des problèmes de tenue. Or, la déformation à chaud utilisée n'implique pas de retour élastique et le relâchement ne s'opère donc pas. Cette déformation à chaud peut être réalisée après une étape de déformation à froid ou inversement.A second embodiment is used in the case where the amorphous alloys having elastic limits that are too high for cold plastic deformation, typically greater than 1500 MPa: The crimping method consists of heating the grains 9 to a temperature greater than the glass transition temperature Tg of the amorphous metal alloy in order to greatly reduce the viscosity and therefore the force required for their deformation. Once the grains 9 at the right temperature, they are deformed so that crimping can take place. A cooling operation is then carried out to solidify them and make the crimping permanent. This solution has the advantage of allowing intimate contact between the amorphous metal alloy and the aesthetic element 3, which improves the resistance of the latter. Indeed, in the case of cold plastic deformation, for both crystalline and amorphous metals, a springback occurs during the relaxation of the force applied to the grain 9. This return inevitably implies a slight separation between the grain 9 and the aesthetic element 3, which can cause problems of holding. However, the hot deformation used does not involve elastic return and release is not therefore performed. This hot deformation can be performed after a cold deformation step or vice versa.

Un troisième mode de réalisation est utilisé lorsque les alliages amorphes sont difficilement sertissables par déformation plastique à froid ou à chaud. Ce mode consiste à profiter de la grande déformation élastique des alliages amorphes, typiquement 2%, contrairement aux alliages cristallins qui se déforment plastiquement à partir de 0.5 %. La méthode consiste à presser l'élément esthétique 3 dans le trou de sertissage 8 du substrat 6. Sous la pression, l'alliage métallique amorphe du substrat 6 se déforme élastiquement permettant à l'élément esthétique 3 de s'insérer. Lorsque les moyens d'accroche 5, se présentant sous la forme d'un évidement de sertissage, et le rondiste ou l'extrémité ou le bord 3a des éléments esthétiques 3 se trouvent en regard l'un de l'autre, un retour élastique s'opère. Le retour élastique des moyens d'accroche 5 sur l'élément esthétique 3 permet de maintenir définitivement celui-ci comme visible aux figures 15 et 16.A third embodiment is used when the amorphous alloys are difficult to crimp by cold or hot plastic deformation. This mode consists of taking advantage of the large elastic deformation of amorphous alloys, typically 2%, unlike crystalline alloys which deform plastically from 0.5%. The method consists in pressing the aesthetic element 3 into the crimping hole 8 of the substrate 6. Under the pressure, the amorphous metal alloy of the substrate 6 is deformed elastically allowing the aesthetic element 3 to be inserted. When the attachment means 5, in the form of a crimping recess, and the rondiste or the end or the edge 3a of the aesthetic elements 3 are opposite one another, a springback takes place. The elastic return of the attachment means 5 on the aesthetic element 3 makes it possible to definitively maintain it as visible to Figures 15 and 16 .

Un quatrième mode de réalisation est également envisagé. Dans ce mode, le support 2 est chauffé thermiquement de façon à ce que tout le support se dilate c'est-à-dire le support 2 et le substrat 6 en alliage amorphe. Par conséquent, le trou de sertissage 8 se dilate également. Par conséquent, l'élément esthétique 3 peut être placé dans le trou de sertissage 8. L'élément esthétique 3 est ensuite maintenu dans le trou 8 par les moyens d'accroche 5 après refroidissement du support 2 comme visible aux figures 17 et 18. Ces moyens d'accroche 5 se présente sous la forme d'un évidement de sertissage dans lequel le rondiste ou l'extrémité ou le bord 3a de l'élément esthétique 3 s'insère.A fourth embodiment is also envisaged. In this mode, the support 2 is heated thermally so that all the medium expands, that is to say the support 2 and the substrate 6 amorphous alloy. As a result, the crimping hole 8 also expands. Therefore, the aesthetic element 3 can be placed in the crimping hole 8. The aesthetic element 3 is then held in the hole 8 by the hooking means 5 after cooling the support 2 as visible to the Figures 17 and 18 . These attachment means 5 is in the form of a crimping recess in which the girdle or the end or the edge 3a of the aesthetic element 3 is inserted.

Un cinquième mode de réalisation peut être envisagé dans lequel la quatrième étape d) et la cinquième étape e) sont simultanées. Ce mode consiste à chauffer l'élément esthétique à une température supérieure à la température de transition vitreuse Tg du premier matériau puis à le presser dans celui-ci c'est-à-dire l'alliage métallique amorphe. La chaleur dégagée par ledit élément esthétique chauffe localement le substrat 6 jusqu'à une température supérieure à Tg qui permet à l'alliage métallique amorphe de voir baisser grandement sa viscosité facilitant ainsi l'insertion Ensuite, une fois l'élément esthétique inséré, le substrat 6 est refroidi pour garder l'état amorphe de l'alliage et est ébavurée de tout surplus de matière. Cette étape permet ainsi une meilleure accroche de l'élément esthétique 3 dans le substrat 6 grâce à la capacité de l'alliage métallique amorphe à bien épouser les contours.A fifth embodiment can be envisaged in which the fourth step d) and the fifth step e) are simultaneous. This mode consists of heating the aesthetic element to a temperature above the glass transition temperature Tg of the first material and then pressing it therein, that is to say the amorphous metal alloy. The heat released by said aesthetic element locally heats the substrate 6 to a temperature greater than Tg which allows the amorphous metal alloy to greatly reduce its viscosity thus facilitating insertion. Once the aesthetic element has been inserted, the Substrate 6 is cooled to maintain the amorphous state of the alloy and is deburred from any surplus material. This step thus allows a better grip of the aesthetic element 3 in the substrate 6 due to the ability of the amorphous metal alloy to marry the contours.

Un sixième mode de réalisation dans lequel la troisième c), quatrième d) et cinquième étape e) sont simultanées. est envisagé. Cette variante consiste à prévoir que l'élément esthétique 3 soit directement placé dans la creusure 4 avant l'étape de remplissage de ladite creusure 4 par le premier matériau. Le remplissage de la creusure 4 se fait alors par coulée, par formage à chaud ou par densification dont les détails ont été expliqués précédemment. Cette technique permet d'avoir un procédé de sertissage plus rapide tout en assurant un bon maintien des éléments esthétiques 3.A sixth embodiment in which the third c), fourth d) and fifth step e) are simultaneous. is envisaged. This variant consists in providing that the aesthetic element 3 is directly placed in the recess 4 before the step of filling said recess 4 with the first material. The filling of the recess 4 is then by casting, by hot forming or by densification whose details have been explained previously. This technique makes it possible to have a faster crimping process while ensuring a good maintenance of the aesthetic elements 3.

Un septième mode de réalisation, caractéristique d'un sertissage invisible, visible aux figures 19 à 23 peut être effectué. Dans ce dernier, le support 2 est muni, dans son fond, d'un trou 30 servant au remplissage. En effet, le procédé consiste à se munir d'une base 200 sur laquelle le ou les éléments esthétique sont placés. Ces derniers sont placés à l'envers. Par exemple, pour un élément esthétique telle une pierre précieuse taillée de sorte à comprendre une culasse dans laquelle sont taillées plusieurs facettes et d'une couronne également facettée surmontée d'une table, la table est en contact avec la base et la culasse pointe vers le haut. Puis, le support 2 est placé de sorte que la creusure 4 soit face à la base et de sorte que le ou les éléments esthétiques 3 soient situés dans l'espace formé par la creusure 4. De préférence, les éléments esthétiques 3 sont situés les uns par rapports aux autres selon leur arrangement définitif. Bien entendu, d'autres dispositifs de pierres peuvent être envisagés, comme par exemple des pierres dont toutes les culasses des pierres pointent vers le bas, ou des pierres disposées de façon aléatoires tels que certaines pierres ont les culasses vers le haut, d'autres ont les culasses vers le bas. Ensuite, le premier matériau c'est-à-dire l'alliage métallique amorphe qui est stocké dans un appareil 300, est versé ou infiltré dans la creusure par l'intermédiaire du trou 30 servant au remplissage. Le premier matériau est ainsi de préférence coulé, injecté ou pressé thermiquement dans ladite creusure 4 puis solidifié pour figer la position des éléments esthétiques 3. Avantageusement, le trou 30 servant au remplissage est également remplit de sorte que, selon son profil, il peut servir de maintien au premier matériau dans la creusure 4. Enfin, la base 200 et le support 2 sont séparés pour obtenir la pièce décorative 1 selon l'invention. Bien entendu, on comprendra que les éléments esthétiques 3 peuvent être mis bord à bord pour éviter que l'alliage métallique amorphe ne soit visible. Dans le cas d'éléments esthétiques 3 taillés pour comprendre une culasse 3b dans laquelle sont taillées plusieurs facettes et une couronne 3c également facettée surmontée d'une table 3d, le fait de mettre les éléments esthétiques 3 bord à bord permet que l'alliage métallique amorphe ne s'infiltre pas entre les couronnes.A seventh embodiment, characteristic of an invisible crimping, visible to Figures 19 to 23 can be done. In the latter, the Support 2 is provided in its bottom with a hole 30 for filling. Indeed, the method consists in providing a base 200 on which the aesthetic element or elements are placed. These are placed upside down. For example, for an aesthetic element such as a precious stone carved to include a breech in which are carved several facets and a crown also faceted surmounted by a table, the table is in contact with the base and the breech point towards the top. Then, the support 2 is placed so that the recess 4 is facing the base and so that the aesthetic element or elements 3 are located in the space formed by the recess 4. Preferably, the aesthetic elements 3 are located to each other according to their definitive arrangement. Of course, other stone devices may be envisaged, for example stones with all the stones' heads pointing downwards, or stones randomly arranged such that some stones have the yokes up, others have the breeches down. Then, the first material, i.e., the amorphous metal alloy that is stored in apparatus 300, is poured or infiltrated into the recess through the hole 30 for filling. The first material is thus preferably cast, injected or thermally pressed into said hollow 4 and then solidified to freeze the position of the aesthetic elements 3. Advantageously, the hole 30 for filling is also filled so that, according to its profile, it can serve maintaining the first material in the recess 4. Finally, the base 200 and the support 2 are separated to obtain the decorative part 1 according to the invention. Of course, it will be understood that the aesthetic elements 3 can be put edge to edge to prevent the amorphous metal alloy is visible. In the case of aesthetic elements 3 cut to include a cylinder head 3b in which are cut several facets and a crown 3c also faceted surmounted by a table 3d, the fact of putting the aesthetic elements 3 edge to edge allows the metal alloy amorphous does not seep between the crowns.

Dans une variante des cinquième à septième modes de réalisation, l'élément esthétique 3 comprend au moins une gorge 31. Cette gorge 31 permet, lors du sertissage de l'élément esthétique, que l'alliage métallique amorphe s'insère dans ladite gorge 31. En effet, comme l'alliage métallique amorphe épouse parfaitement les contours d'une pièce lorsqu'il est chauffé à une température supérieure à Tg ou lorsqu'il est liquide, la gorge 31 fait alors office de moyen permettant d'ancrer l'élément esthétique dans le substrat 6 en métal amorphe comme visible à la figure 23.In a variant of the fifth to seventh embodiments, the aesthetic element 3 comprises at least one groove 31. This groove 31, during crimping of the aesthetic element, the amorphous metal alloy is inserted into said groove 31 Indeed, since the amorphous metal alloy perfectly matches the contours of a room when it is heated to a temperature greater than Tg or when it is liquid, the groove 31 then acts as a means of anchoring the room. aesthetic element in the substrate 6 of amorphous metal as visible in the figure 23 .

Un avantage de l' invention est qu'elle permet de sertir n'importe quel type de matériaux. En effet, le principe utilisé est un principe de pièce rapportée c'est-à-dire qu'un substrat en matériau pouvant accepter une déformation est rapporté dans un matériau non déformable plastiquement de sorte à permettre un sertissage et à donner l'illusion que c'est ce matériau non déformable plastiquement qui est serti.An advantage of the invention is that it can crimp any type of material. Indeed, the principle used is an insert principle that is to say that a substrate material capable of accepting a deformation is reported in a material that is not plastically deformable so as to allow crimping and to give the illusion that it is this non-plastically deformable material that is crimped.

Dans une première variante visible à la figure 14, le maintien du premier matériau est amélioré par utilisation de moyens de maintien 50. Ces moyens de maintien 50 comprennent au moins un évidement 51 et/ou au moins un excroissance 52. Ces moyens de maintien 50 sont réalisés au préalable au remplissage de la creusure 4. De ce fait, lors du remplissage de ladite creusure, le premier matériau rempli les évidements 5a ou les excroissances 5b deviennent prisonnières dudit premier matériau. En conséquence, lorsque le premier matériau rempli la creusure 4 et est solidifié, il est parfaitement maintenu dans ladite creusure 4.In a first variant visible at the figure 14 , the maintenance of the first material is improved by using holding means 50. These holding means 50 comprise at least one recess 51 and / or at least one protrusion 52. These holding means 50 are made prior to the filling of the recess 4. Thus, during the filling of said recess, the first material filled the recesses 5a or 5b protuberances become trapped in said first material. Consequently, when the first material fills the recess 4 and is solidified, it is perfectly maintained in said recess 4.

Dans le cas où le premier matériau est un alliage métallique amorphe, la faible viscosité du matériau amorphe permet de bien remplir la creusure 4. Par analogie, cette faible viscosité du matériau amorphe permet également de mieux remplir les évidements 51 ou de mieux envelopper les excroissances 52.In the case where the first material is an amorphous metal alloy, the low viscosity of the amorphous material makes it possible to fill the recess 4. By analogy, this low viscosity of the amorphous material also makes it possible to better fill the recesses 51 or to better envelop the excrescences. 52.

Ces évidements 51 ou excroissances 52 peuvent être situés sur les flancs verticaux 7 de la creusure 4 ou au niveau du fond 7a de la creusure 4. De même, les évidements 51 peuvent être traversant ou non.These recesses 51 or protuberances 52 may be located on the vertical flanks 7 of the recess 4 or at the bottom 7a of the recess 4. Similarly, the recesses 51 may or may not be through.

On comprendra que diverses modifications et/ou améliorations et/ou combinaisons évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention exposée ci-dessus sans sortir du cadre de l'invention défini par les revendications annexées.It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the various embodiments of the invention set forth above without departing from the scope of the invention defined by the appended claims.

Ainsi, il est envisageable qu'une fois le métal amorphe est mis en forme dans le creusure 4, une étape de cristallisation ait lieu juste avant ou juste après l'étape de réalisation des trous de sertissage 8. Cette étape consiste à chauffer le métal amorphe au-dessus de sa température de transition vitreuse Tg durant un temps suffisamment long pour que la cristallisation puisse s'opérer. Une fois cristallisé l'alliage peut être refroidi. Les paramètres de cristallisation (temps et température) doivent être choisis de manière à assurer la croissance de phase(s) cristalline(s) ductile(s) et non fragile(s). Cela permet de profiter des propriétés de mise en forme du métal amorphe et de profiter de la facilité des métaux cristallins à se déformer plastiquement notamment à froid.Thus, it is conceivable that once the amorphous metal is shaped in the hollow 4, a crystallization step takes place just before or just after the step of making the crimping holes 8. This step consists in heating the metal amorphous above its glass transition temperature Tg for a time long enough for crystallization to take place. Once crystallized the alloy can be cooled. The crystallization parameters (time and temperature) must be chosen so as to ensure the crystalline phase (s) crystalline (s) ductile (s) and not brittle (s). This makes it possible to take advantage of the shaping properties of the amorphous metal and to take advantage of the facility of the crystalline metals to deform plastically, especially when cold.
