- Abstract
Results of analytical and experimental studies of the effect of annealing in vacuum on the limit of elasticity of nonferrous alloys are presented. Vacuum annealing changes the chemical composition of the surface layers due to sublimation of the highly volatile component of the alloy, which leads to a decrease in its limit of elasticity due to the accumulation of crystal structure defects. An empirical equation is suggested for predicting the variation of the limit of elasticity of heterophase alloys as a function of the duration of isothermal annealing in vacuum. The results obtained by solving this equation agree satisfactorily with experimental data.
