Abstract

A statistical method of experiment planning was used to determine the hardening treatment conditions of KhN77TYu alloy ensuring the maximum time-to-rupture at a stress of 36 kg/mm2 acting at 700° C. The influence of preliminary deformation and post-deformation annealing time and temperature on the hightemperature strength of the alloy studied was analyzed with the aid of a mathematical model of the hardening process.
