Definitions

the present invention relates to nickel-based alloys, comprising chromium and aluminum and allowing precipitation hardening by heat treatment.
a family of nickel-based alloys with a high chromium and aluminum content is known from patent FR 1,267,470 in which precipitation hardening is obtained following a solution treatment followed by 'income.
the dissolution treatment of the intermetallic hardening phases makes it possible to reach sufficiently low hardness levels so that the metal is easy to shape.
the temperature at dissolution should exceed 1100 ° C or even 1150 ° C to furthermore cure during tempering. Maintaining at a temperature above 1100 ° C can cause excessive grain enlargement. A grain that is too coarse leads to irregular surface conditions during shaping operations and makes certain machining operations difficult and especially gives the metal great brittleness after hardening.
the object of the present invention is to provide a family of alloys of the above type in which the presence of ferrite improves ductility.
the alloys have good resistance to oxidation and corrosion, high mechanical strength and a very high elastic limit and great hardness after heat treatment.
alloys comprising by weight 28 to 42% of chromium, less than 25% of iron, 3 to 5% of aluminum, nickel making the balance with the usual impurities, the contents of iron and chromium situated in the area marked I of the diagram in FIG. 1, said alloys having ferrite at dissolution temperatures in order to control the size of the grain.
a particular composition comprises by weight 37 to 38% of chromium, 7 to 8% of iron and 3 to 5% of aluminum, 50 to 51% of nickel.
the alloys according to the invention are produced by the methods of conventional metallurgy (by casting) or by powder metallurgy. They exhibit precipitation hardening after tempering following a solution treatment. The hardening is caused by the discontinuous (or cellular) precipitation of the ⁇ 'Ni 3 Al phase.
Chromium is favorable for corrosion resistance and contributes to the formation of the ⁇ phase with a centered cubic structure (called ferrite).
the chromium content must be greater than 28 X and the iron content must be less than 25 X and for the brittleness of the alloy not to be excessive, the content of chromium chromium does not exceed 42%.
the cellular precipitation of ⁇ 'phase is more and more slower and less and less complete.
the relative contents of chromium and iron must be adjusted so that the alloys according to the invention have, at the usual dissolution temperatures (above 1100 ° C.) a sufficient but not excessive amount of the ⁇ phase.
the zone I the outline of which is marked ABCD defines the field of the compositions according to the invention which have a sufficient quantity of phase ( ⁇ to slow down the magnification of the grain upon dissolution.
the compositions do not have enough ferrite to slow down the magnification of the grain during dissolution.
zone III located above DC the compositions have too much ferrite which decreases the alloy ductility.
Aluminum contributes to give good resistance to corrosion and is used to form the hardening phase ⁇ '.
the content of this element must be greater than 3% for the precipitation hardening to be sufficient and must be less than 5% to avoid difficult manufacture or excessive brittleness.
An alloy N of the family according to the invention has been studied, by way of example, and for comparison, an alloy A having no ferrite.
the compositions which are given in Table I below are expressed in percentages by weight.
the analyzes of the alloys above reveal non-essential elements which may result from processing, the contents not exceeding 0.05% for each of these elements.
the alloys were tested in tension. To this end, the alloy N has undergone a solution treatment at 1200 ° C. followed by a quenching with water which has made it possible to obtain a grain of 9.5 ASTM. Alloy A underwent a solution treatment at 1225 ° C followed by quenching with water which made it possible to obtain a grain of - 3 ASTM. The alloys then underwent income hardening at temperatures between 650 ° C and 800 ° C for several hours. Depending on the tempering conditions, the alloys have a high hardness which ranges from around 500 HV to more than 700 HV. These different treatments make it possible to adjust the elastic limit.
the alloys according to the invention can be used for applications requiring high mechanical strength with excellent corrosion resistance and also requiring high ductility. As possible applications, mention may be made of structural parts requiring high ductility (bolts, casing, turbine disc, etc.).
