N2 - Based on the temperature relaxation model of plasticity, the effects of the irreversible deformation of metals that appear under conditions of various temperature and strain rate regimes are studied. The appearance of the yield drop on the dynamic deformation dependence for 2519А aluminium alloys at a temperature of -45°C in the range of strain rates 1000–4000 s–1 is predicted. Dynamic dependencies for Al-13Mg aluminium alloys at temperatures 325°C and 425°C are constructed. The temperature relaxation model of plasticity applied is able to predict various types of deformation curves for on one material in a wide range of strain rates and temperatures.
