Autowave Description of the Temperature Effect during Deformation of FCC Metals

The data of comparative studies of the development of plastic flow in pure aluminum and iron-based austenitic alloy (Fe–Cr–Ni) are presented. Deformation patterns were studied during tests in the temperature range 143 \( \leqslant \) T \( \leqslant \) 420 K. It was found that the effect of temperature is different for these two cases. When a stationary dissipative structure appears at the stage of parabolic strain hardening, the effect of temperature is determined by the change in the length of the localized plasticity autowave. At the stage of linear strain hardening, when a phase autowave of localized plasticity is formed, the effect is associated with an exponential increase in its rate with temperature.
