Definitions

  • the invention relates to a light precious alloy based on titanium and gold, comprising at least 750 ⁇ by mass of gold.
  • the invention also relates to a timepiece or jewelry component made of such a light precious alloy based on titanium and gold.
  • the invention relates to the field of structural components or clocks for watches or jewelry in 18 carat gold alloy.
  • a characteristic common to most precious alloys used in watchmaking is their high density, greater than 10 g / cm 3 . Indeed, the two main precious metals used in watchmaking, gold and platinum, have respective densities of approximately 19.3 and 21.5 g / cm 3 . This has the consequence of making their alloys relatively heavy.
  • Titratable gold alloys are usually very dense due to their high gold content, and due to the fact that they rarely incorporate light elements in large quantities. It is also usual to arrive at fragile compounds if we combine gold with light elements in large quantities.
  • the Ti-Au system has nonetheless been studied, in the TiAu equi-atomic intermetallic zone.
  • alloys in their binary or ternary form, are known to exhibit a shape memory effect, in particular alloys having the atomic compositions Ti 50 Au 50 and Ti 50 Ni 10 Au 40 .
  • the temperature M s has also been reduced following the addition of ternary elements to the Ti 50 Au 50 alloy.
  • TiAuFe alloys with 5, 10, 14, 15 and 20 atomic% of iron, and the TiAuCo and TiAuCoNb alloys, have been the subject of specific studies, without exploitable results for the problem posed.
  • EP2548982A1 discloses alloys containing from 50% to 99% of titanium, and more precisely alloys containing a single precious element in addition to titanium, ideally located between 5 and 15% of precious metal. It is noted that an alloy of titanium and gold containing 5 to 15% of gold cannot be titrated to 18 carats, because the required mass proportion of 75% of the total in gold is not reached.
  • the document WO 2008 / 018109A1 describes titanium and gold alloys titratable between 6 and 18 carats, with shape memory, which is not desired, or super-elastic, and having a certain elongation at break. Most of these alloys are compositions containing nickel, which is not desirable for the production of external components of timepieces or jewelry, likely to come into contact with human skin. This document discloses only two 18-carat compositions: Ti 11.23 Ni 13 . 77 Au 75 and Ti 12.5 Ni 12.5 Au 75 by mass. These two compositions are very far from an atomic content of 50% of titanium and contain nickel, they are not suitable for use in watchmaking.
  • the document WO2010 / 027329 in the name of AUTIUM describes Au-Ti-X alloys where X represents at least one element among the approximately 115 elements of the periodic table, with, in particular variants, Ti greater than 10% by mass, or Ti between 10 and 50% by mass, or Au between 58 and 85% by mass, or an element X to be taken from Fe, Co, Cr, Mn, Mo, Pd, Nb, W, Al, Si, with contents up to '' at 8% by mass.
  • the disclosed ranges are extremely wide, and, although they may cover alloys with some ductility, do not indicate how to achieve this and do not indicate a possible tight preferential range within the widest compositions.
  • the document GB876887 on behalf of DEGUSSA describes gold alloys for electrical resistances, in particular of the Au-Ti-Fe type containing from 1 to 5% by mass of titanium.
  • dental alloys comprising 50-91% by mass of gold, 9-50% by mass of titanium, binary or containing 0-20% by mass of platinum and / or palladium and / or 0-15% of others elements suitable for dental alloys: silver, copper, vanadium, iron, aluminum, niobium, tantalum, gallium, among others. More particularly, a variant limits platinum and palladium to a maximum of 10% by mass, and the other elements also to 10% by mass. And another variant contains, by mass, 50-83% gold and 17-50% by mass of titanium.
  • a particular mass composition Ti42.2Au57.8 disclosed by this document relates to the brittle and fragile intermetallic compound of atomic composition Ti 3 Au, and is not advantageous for the manufacture of components for watchmaking.
  • the metallurgist knows that the properties of an alloy are strongly influenced by its microstructure, yet the teachings of this document vary from one extreme to another from this point of view.
  • This document indicates only approximate compositions, with very wide ranges of gold, titanium and addition elements, which mainly lead to compositions unsuitable for the intended horological use, and dropping it from these ranges covers number of possible alloys, without this document disclosing any specific indication relating to the interest of particular ranges.
  • the invention proposes to develop a titratable alloy with 18 carat gold, which is easy to shape to allow the production of components for clocks, watches or jewelery, such as watch cases, bracelets , jewelry or the like, and which is also lighter than a traditional gold alloy while having very good mechanical properties, as can be had with titanium alloys.
  • the invention relates to a light precious alloy based on titanium and gold, comprising at least 750 ⁇ by mass of gold, according to claim 1.
  • the invention also relates to a timepiece or jewelry component made of such a light precious alloy based on titanium and gold.
  • the present invention consists of a ductile alloy based on the equi-atomic intermetallic TiAu in which the surplus of gold relative to the mass by weight of 18 carats is replaced by another non-precious element so that titanium represents always 45 to 55 atomic% of the final alloy and 750 ⁇ gold by mass (i.e. 18 carats).
  • a ductile alloy based on the equi-atomic intermetallic TiAu in which the surplus of gold relative to the mass by weight of 18 carats is replaced by another non-precious element so that titanium represents always 45 to 55 atomic% of the final alloy and 750 ⁇ gold by mass (i.e. 18 carats).
  • Such an alloy has sufficient ductility to offer a formability similar to that of conventional titanium alloys.
  • Parameter "a” defines the fraction of titanium.
  • the "b” parameter defines the fraction of gold.
  • Parameter "c" defines the total fraction of M elements.
  • the "d” parameter defines the total fraction of the T elements.
  • the alloy contains 750 ⁇ by mass of gold. This proportion by mass of the total of the alloy does not naturally come into contradiction with the atomic proportions of the elements of alloy, it is about an additional condition related to the title, and which is not at all incompatible with the compositions of alloy described in the present invention.,
  • nickel is excluded from the alloy, and the formulation is restricted with regard to T, which represents a maximum of two elements taken from a third group corresponding to the second group from which the nickel is removed, and comprising: Nb, V, Mo, Ta, W, Fe, Co, Ru, Rh, Ir, Pd, Pt, Cr, Mn, Cu, Zn, Ag, Al, B, Si, Ge, Sn, Sb, In, with the exception of the metals M which this alloy contains.

  • the interval 0.50-0.51 for the atomic fraction of titanium corresponds to the stability interval of the equiatomic intermetallic phase TiAu at room temperature in the binary system Ti-Au.
  • T represents a maximum of two elements taken from a fourth group more restricted than the third group and comprising: Nb, V, Fe, Ru, Rh, Ir, Pd, Pt, Cr, Cu, Ag, B, to with the exception of the metals M which this alloy comprises.
  • M represents one or more elements belonging to a fifth group corresponding to the first group from which the vanadium is removed and comprising: Nb, Pd, Fe.
