Abstract: | Yield point, hardening factor, and elastic modulus are reported as functions of quenching and test temperatures for the alloys Ni3(Fe + 3 at% Al), Ni3(Fe + 3 at% Mn). A maximum is found in the mechanical properties near the critical temperature Tcr; this does not occur for alloys in the disordered state. The deformation aging under load is examined near this maximum and at 200 ° C. A range of linear hardening occurs up to e of 15–18% in ordered alloys, which is replaced by a range of decreasing hardening coefficient at higher . The results are discussed by reference to earlier ones for Ni3Fe, Ni3(FeCr). Ni3(FeMo). |
