Definitions

  • the present invention relates to a new family of nickel-based superalloys having the properties noted above, characterized in that the chemical composition in weight percentages, belongs to the following field: the remainder being essentially nickel.
  • these superalloys according to the invention are capable of being implemented by powder metallurgy techniques and the turbomachine disks constitute an interesting application.
  • the nickel-based superalloys generally have an essentially two-phase structure with: - a phase y of Ni, Co hardened mainly by elements in solid solution (W, Cr, Mo) - a hardening phase y of type A s B in which A is mainly formed of Ni, Co, Cr and B of AI, Ti Nb, Ta, Hf, V, Ta.
  • Tantalum also has, with respect to niobium, the disadvantage of increasing the density more strongly.
  • the alloys of the present invention do not contain Ta and are limited to 1.5% of Nb.
  • the invention provides contents of AI and Ti such that their ratio is close to 1 because, if it is known that Ti is a more favorable element than AI for the curing of the y phase beyond 650 ° C, it very quickly increases the solid solution re-temperature of this phase, making the implementation of the alloy difficult. For the same reason the sum of the elements AI + Ti is limited to 10% by weight.
  • Additional hardening may be obtained by the addition of Hf, up to a limit of 1% for processing reasons (reduction of the solidus and increase of the solvus Y).
  • the alloys of the present invention do not contain vanadium.
  • the present invention recommends a Mo content of between 6 and 8% by weight which, as shown in Table 2 (see in particular the examples of alloys according to the invention N 14 and N 16), results in high resistance values in tension and creep, the alloy nevertheless retains particularly low cracking fatigue-creep rates.
  • the invention recommends a chromium content of between 11 and 13% by weight.
  • Boron and carbon are known elements which can improve the creep resistance, but taking into account the chromium and molybdenum contents of the invention, and in order to avoid the excessive formation of carbides and borides, the invention limits their concentration by weight at 500 ppm.
  • Zirconium may be useful for fixing possible embrittling traces of sulfur, but the invention however limits its content to 500 ppm by weight to avoid the formation of phases with a low melting point.
  • Other elements such as Mg, Ca, Si, Y etc ... often used for the development of the alloy, can remain present at the level of traces without harming the properties of the alloys according to the invention.
  • superalloys in accordance with the invention can use any method such as to avoid the appearance of major segregations of the kind which appear when such alloys are used according to conventional foundry methods.
  • production of superalloys according to the invention can in particular be obtained by the known techniques of powder metallurgy and parts made of these alloys such as turbomachine rotor discs can for example be manufactured by known isostatic compaction processes with hot.
