Definitions
- the invention relates to the field of rolled or extruded products, such as sheets, strips, tubes, bars, wires or profiles, of aluminum alloy of the AlMgMn to Mg type> 3% in weights, intended for welded constructions requiring, in addition to an elastic limit high, good resistance to fatigue and good toughness, good corrosion resistance for structural applications, such as for example boats, offshore constructions or industrial vehicles.
- the heat affected area around the weld joint is in the annealed state (state O), with less mechanical characteristics, this which does not allow to fully exploit, in welded constructions, the mechanical characteristics of the material.
- European patent application EP 0385257 (Sumitomo Light Metal Industries Ltd) claims the application of a processing method complex and unreliable thermomechanical to an alloy containing, inter alia, from 4.0 to 6.0% magnesium and 0.1-1.0% manganese.
- the target application is not that of mechanical engineering, but that of the cover for boxes; the technical characteristics (notably resistance to pitting corrosion) of this product compare favorably to those of products known for this application, but do not meet the requirements of mechanical engineering welded.
- German patent application DE 2443443 (Siemens AG) claims a component weldable aluminum alloy machine, containing, inter alia, 3.5 to 4.9% of Mg and 0.5 to 1.5% Mn. No information is given on the characteristics mechanical or corrosion resistance of this product.
- European patent application EP 0507411 (Hoogovens Aluminum) describes the application of a complex thermomechanical treatment range to an alloy AlMgMn containing, inter alia, 0.8 to 5.6% Mg, up to 1% Mn and some other elements such as Fe, Ni Co, Cu, Cr and Zn.
- the product thus obtained is characterized by good formability, in particular good elongation at break, and the absence of Lüders lines. It does not meet the needs of welded construction resistant to corrosion.
- European patent EP 0015799 (aines et Chantiers de Bretagne) discloses a weldable alloy containing inter alia 3.5 to 4.5% magnesium and 0.2 to 0.7% manganese for the manufacture of tubes for cryogenic application. This application does not pose the problem of thermal sensitization to corrosion, and the document does not mention mechanical characteristics or other properties use of the product.
- French patent application 95-12065 relates to a particular composition alloy, subsequently registered with the Aluminum Association under the designation 5383, containing inter alia 3 to 5% of magnesium and 0.5 to 1% of manganese, in which the sum of the contents (in% by weight) Mn + 2Zn is> 0.75.
- This composition makes it possible to obtain rolled or spun products having resistance to significantly better fatigue and crack propagation speed significantly smaller than known products intended for the same application.
- the cited patent application gives no indication of the resistance to corrosion of the product.
- the alloy was presented in a communication entitled "New Aluminum Products for High-Speed Light Crafts" by G.M. RAYNAUD at Second International Forum on Aluminum Ships in Melbourne November 22-23 1995.
- French patent application 95-12466 claims a very narrow composition, to the inside of the composition ranges of alloys 5083 and 5086, containing between other 4.3 to 4.8% magnesium and less than 0.5% manganese, allowing to obtain good characteristics during large deformations. This request does not Nor does it mention corrosion resistance.
- the problem to which the present invention attempts to respond is therefore to propose rolled, extruded or drawn products of AlMgMn alloy having, after welding, a improved corrosion resistance and better resistance to the sensitizing effect of temperature exposure, while retaining good mechanical properties after welding, good resistance to fatigue and can be developed at the lowest cost.
- AlMgMn alloys can be made more resistant to the sensitizing effect of exposure to temperature when they a particular and well-defined microstructure, which results from a set of manufacturing process parameters.
- the subject of the invention is therefore a product of AlMgMn alloy for welded mechanical construction of composition (% by weight): 3.0 ⁇ Mg ⁇ 6.5 0.2 ⁇ Mn ⁇ 1.0 Fe ⁇ 0.8 0.05 ⁇ Si ⁇ 0.6 Zn ⁇ 1.3 optionally Cr at a content ⁇ 0.15 and / or one or more of the elements Cu, Ti, Ag, Zr, V, at a content ⁇ 0.3 each, the other elements being ⁇ 0.05 each and ⁇ 0.15 in total, in which the number of Mg 2 Si particles with a size between 0.5 and 5 ⁇ m is between 150 and 2000 per mm 2 , and preferably between 300 and 1500 per mm 2 .
- the microstructure has a preponderant influence. More specifically, in the high magnesium content domain, i.e. above about 5%, the the material's thermal sensitivity to corrosion is considerably reduced. This better corrosion resistance allows more incorporation of magnesium to achieve mechanical properties equivalent to those of known AlMgMn alloys but unsuitable for use in corrosive environments.
- the eutectic phases Mg 2 Si the eutectic phases AlFeMnSi, the eutectic phases Al 6 (Mn, Fe) and AlFeCr, and the manganese dispersoids, noticeably submicron size, found in the grain.
- the particular microstructure according to the invention is characterized by a new distribution in size and quantity of these known phases.
- This microstructure was characterized in the following manner, well known in micrography. A polished section of the metal is prepared and observed by optical microscopy or scanning electron microscopy. Light microscopy easily identifies the Mg 2 Si phases compared to the other phases present. Scanning electron microscopy lends itself better to characterizing phases smaller than 0.5 ⁇ m; using the backscattered electron mode, it also makes it possible to distinguish the Mg 2 Si phases.
- the Mg 2 Si phases contain most of the silicon present in these alloys, and that these phases are, in particular in alloys exceeding 3 to 4% of Mg, practically insoluble (see LF Mondolfo, "Aluminum Alloys, Structure and Properties ”, London 1976, p. 807). Consequently, their number and their size are determined during casting and practically do not change during the thermomechanical treatment of the product, provided that the melting temperature (burn) of these phases which constitute the most fusible eutectic.
- the silicon content corresponds to the level of impurity of the base metal.
- the Applicant has found that the increase in the number of small Mg 2 Si particles (size from 0.5 to 5 ⁇ m) leads to an unexpected improvement in the corrosion resistance, both of welded structures and of raw sheets. This effect is particularly marked when the number of Mg 2 Si particles is between 150 and 2000 particles / mm 2 and, preferably, between 300 and 1500 per mm 2 . Above 2000 particles per mm 2 , no additional effect on the corrosion resistance is observed; in some cases, there is even a drop in the elastic limit after welding. Furthermore, it has found that by reducing the size of the Mg 2 Si particles, the fatigue resistance of the welded joints is improved.
- the number of “large” particles must represent only a reduced part of the totality of the particles (of size> 0.5 ⁇ m), typically less than 25%, and, preferably, less than 20%.
- the surface fraction of the Mg 2 Si particles also measured by image analysis from optical microscopy, must be less than 1%, and preferably less than 0.8%.
- the eutectic phases AlFeMnSi, Al 6 (Mn, Fe) and AlFeCr contain part of the Mn, Si and Cr present in the alloy and do not participate in the hardening of l alloy or its resistance to corrosion. They trap part of the Mn, Cr and Si. It is known that these phases are insoluble and their size, number and morphology are determined during casting.
- the Applicant has found that by reducing the size and the number of these phases, the fatigue life and the mechanical properties of the metal are improved.
- the number of particles of this type of size> 0.5 ⁇ m must be less than 5000 per mm 2 , and preferably less than 2500 per mm 2 .
- the surface fraction of particles with a size> 0.5 ⁇ m must be ⁇ 3%, and preferably 2%, knowing that the number of large particles with a size greater than 5 ⁇ m must not represent more than 25% (preferably 20 %) of all particles of size> 0.5 ⁇ m.
- a decrease in the volume fraction of these eutectic phases leads to an improvement in the corrosion resistance.
- dispersoids Al, Mn, Fe, Cu
- dispersoids Al, Mn, Fe, Cu
- the Applicant has observed a strong effect of the fraction of dispersoids on corrosion resistance: the sensitizing effect of exposure to temperature is greatly reduced when the surface fraction of dispersoids exceeds 0.5%, and preferably 1%.
- magnesium provides good mechanical strength. Below 3.5%, and more particularly below 3.0%, the alloy does not know in general no corrosion problem and the present invention presents only a little of interest. Above 6.5%, the problem of thermal sensitization to corrosion becomes so strong that even the implementation of the present invention no longer makes it possible to obtain products which can be used in a corrosive environment.
- Manganese improves tensile strength and decreases the tendency of the metal to recrystallize, which is known to those skilled in the art. Below 0.2%, the present invention is of no industrial interest because the tensile strength is too low. Above 1%, elongation at break, toughness and resistance to fatigue become too weak for the intended applications.
- Zinc in the presence of manganese, improves breaking strength, but beyond from 0.5 to 0.7%, the applicant observed, by studying behavior at the corrosion, especially in the marine environment, of the welded joint after aging, some failure. For zinc contents greater than 0.5%, it therefore appears necessary to protect the welded joint from contact with corrosive medium, for example by painting or metallization. It has been found that the presence of 0.2 to 0.3% zinc increases magnesium content without increasing thermal sensitivity of exfoliating corrosion material.
- Copper and chromium also have a favorable effect on the elastic limit, but the chromium content must imperatively be limited to 0.15% to maintain good resistance to fatigue.
- the copper content is strictly limited to 0.30% and does not should preferably not exceed 0.18% to avoid the appearance of bites corrosion in a corrosive environment.
- the iron content does not have much influence in the context of the present invention; it should be less than 0.8% to avoid the formation of primary phases during casting, whereas for high manganese contents, it is preferable that it does not not exceed 0.4%.
- the silicon content must be sufficient to ensure the formation of silicon phases such as Mg 2 Si, and at least 0.05%, but must not exceed 0.6%.
- the alloy may also contain, for certain applications, titanium, silver, zirconium or vanadium in an amount less than 0.3%.
- Another subject of the invention relates to the manufacture of products having the microstructure described above in the form of wide hot-rolled strips, of width greater than 2500 mm, preferably of width greater than 3300 mm.
- Such a width means that cold rolling is to be abandoned, since the rolling mills cold are not designed to allow rolling to such a width. This wants to say that one obtains the strip or the sheet having all the characteristics described directly by hot rolling, which is possible with the invention.
- the products according to the invention have a high yield strength after welding, which of course depends on the Mg content, and which is greater (in MPa) than 40 + 20 x% Mg.
- the deformation when cutting the sheets, measured in the H22 state after leveling and traction, is less than 3 mm; without traction, that is to say only after leveling, it is less than 5 mm.
- Examples 1 and 2 in accordance with the invention, and Example 3 (resulting in a microstructure outside the invention) correspond to composition 1.
- Examples 4 and 5 in accordance with the invention, and Example 6 (resulting in a microstructure outside the invention) correspond to composition 2.
- Example 7 and 8 in accordance with the invention, and Example 9 (resulting in a microstructure outside the invention) correspond to composition 3.
- Example 10 (resulting in a microstructure outside the invention) corresponds to the composition 4 which is outside the scope of the invention.
- the plates After reheating for 20 h at a temperature above 500 ° C, the plates were hot rolled to a final thickness of 14 mm.
- the laminated sheet samples were characterized by techniques known to those skilled in the art.
- the tensile strength R m and the elastic limit R 0.2 were measured on these sheets. These measurements make it possible to globally assess a first aspect of the product's suitability for the intended use, the present invention however not relating to an improvement in static mechanical characteristics.
- the number, the surface fraction and the size distribution of eutectic precipitates Mg 2 Si and AlFeMnSi were measured by image analysis.
- samples were prepared by a shipyard company by automatic continuous butt MIG welding, with a symmetrical chamfer of slope 45 ° with respect to the vertical over a thickness of 6 mm, with wire. addition of alloy 5183. Welding was carried out parallel to the direction of rolling.
- Corrosion resistance was measured by weight loss after immersion and by measuring the depth of intergranular corrosion.
- the immersion was carried out in the “inter-acid” bath described in the Official Journal of the European Community of September 13, 1974 (n ° C 10484). It is an immersion for 24 hours in a bath composed of NaCl (30 g / l), HCl (5 g / l) and distilled water, at a temperature of 23 ° C ⁇ 0.5 ° C, the liquid volume being greater than 10 ml per cm 2 of sample surface.
- the samples were subjected to thermal sensitization by heating at 100 ° C for a period varying between 1 and 30 days.
- the deformation on cutting was measured as follows: From a sheet with a width of 2000 mm and a length of 2500 mm in the H22 state, a strip of width 130 mm is cut by sawing in the middle parallel to its length. This strip is placed on a marble, and the deformation of the raised ends is measured, expressed by the difference between the edge of the strip and the surface of the marble.
- Table 3 indicates the microstructure observed, and Table 4 collates the results of the other characterizations carried out. ex. number of phases Mg 2 Si of 0.5-5 ⁇ m % phases Mg 2 If size> 5 ⁇ m surface fraction. Mg 2 If% nb.part. AlFeMn CrSi 0.5-5 ⁇ m % go. AlFeMn CrSi 0.5-5 ⁇ m Fr. surf. AlFeMn CrSi% Fr. surf.
- examples 1, 2, 4, 5, 7 and 8 are distinguished by a depth of particularly weak puncture compared to examples 3, 6 and 9 corresponding to the prior art, and with respect to example 10, which itself gives the bad result that we expect a high magnesium content AlMgMn alloy developed according to the art prior.
- Example 10 cannot be used because of its low resistance to corrosion.
- the very good resistance of the sheet of Example 7 can allow it to applications in welded construction intended for a highly corrosive environment and constitutes an improvement compared to the prior art represented by example 9.

C'est pour cette raison qu'il existe dans la norme NF EN 515 un état métallurgique spécifique (H116) pour les alliages de la série 5000 contenant au moins 4 % de magnésium, auquel s'attachent des limites de caractéristiques mécaniques et une résistance à la corrosion exfoliante spécifiés.

Pour déterminer la taille des particules, on évalue, par analyse numérique des micrographies, leur aire A à partir de laquelle on calcule le paramètre de taille d selon la formule d =
Il est bien connu que les phases Mg2Si contiennent la plus grande partie du silicium présent dans ces alliages, et que ces phases sont, en particulier dans les alliages dépassant 3 à 4 % de Mg, pratiquement insolubles (voir L.F. Mondolfo, « Aluminium Alloys, Structure and Properties», London 1976, p. 807). Par conséquent, leur nombre et leur taille sont déterminés lors de la coulée et n'évoluent pratiquement pas au cours du traitement thermomécanique du produit, à condition que l'on n'atteigne pas la température de fusion (brûlure) de ces phases qui constituent l'eutectique le plus fusible. La teneur en silicium correspond au niveau d'impureté du métal de base.
