The behavior of the localized plastic flow autowaves characteristics is considered in the Fe-Ni-Cr alloy for the temperature range from 143 K to 420 K (420 K is the Debye temperature). It is shown that the multiplication of the autowave length and the velocity of its propagation, in the specified interval, decreases with temperature. At the same time, the ratio of this value to the viscosity of the phonon gas in the metal in the investigated temperature range remains practically constant. This indicates that the elastic-plastic invariant of deformation is independent of temperature.
