The temperature dependence of the autowave mechanism of plastic flow

The behavior of characteristics of localized plastic flow autowaves in a Fe–Cr–Ni alloy in the temperature interval of 143 $\le T\le$ 420 K (0.34 $\le T/\Theta_{D}\le$ 1), where $\Theta_{D}$ = 420 K is the Debye temperature (parameter), is considered. It is shown that the product of the length and propagation rate of the autowave $\lambda V_{aw}$ 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.
