FIELD: study of physico-mechanical properties of metals. SUBSTANCE: process includes heating of samples of compared alloys to three temperatures as minimum in interval 190-220 C, cooling and determination of mechanical properties at room temperature after each heating. Duration of each heating at stage of overranging till constant preset value of strength characteristic is achieved is found by kinetics of softening of compared alloys. Dependence of heating duration on temperature is found per each alloy by relation lgτ = a+bt,; where t is heating temperature, C; τ is duration of heating, h; a, b are coefficients of regression obtained by method of least squares. Optimal region of normal functioning of each alloy is judged after comparison of these relations by longer duration of heating. EFFECT: improved authenticity of process. 6 dwg, 1 tbl
