Abstract

The behavior of characteristics of localized plastic flow autowaves in a Fe–Cr–Ni alloy in the temperature interval of 143 ≤ T ≤ 420 K (0.34 ≤ T/Θ_D ≤ 1), where Θ_D = 420 K is the Debye temperature (parameter), is considered. It is shown that the product of the length and propagation rate of the autowave λV_aw in this interval decreases with temperature. At the same time, the ratio of this quantity to viscosity of the photon gas in the metal in the investigated temperature interval remains almost constant. This indicates that the elastoplastic strain invariant does not depend on temperature.

塑性流自动波动机理的温度依赖性

摘要

在143≤的温度间隔的Fe-Cr-Ni合金的局部塑性流动autowaves的特性的行为Ť ≤420 K（0.34≤ Ť /Θ _d ≤1），其中Θ _d = 420，K是德拜温度（参数）。结果表明，该自动波λ的长度和传播速率的乘积V _AW在此区间随着温度而降低。同时，在所研究的温度区间中，该数量与金属中光子气体的粘度之比几乎保持恒定。这表明弹塑性应变不变性不依赖于温度。
