Analysis of dispersion hardening of nickel-based alloys

Аннотация

This article describes a procedure for calculation and construction of the yield point as a function of average particle size of the Ni₃Al phase at 750, 850, and 950°C. The developed approach can be applied to thermally hardenable alloys and is related to nucleation of intermetallic phases. This procedure of calculation and analysis of dispersion hardening facilitates selection of optimum modes of thermal treatment aimed at production of preset particle size of phases, determining maximum hardening of aging alloys.
