The elastic limit and tensile strength of deformed magnesium alloys Ma2 1 with different struc tures and textures were measured with the aim of finding a correlation between the spectrum of defects in the material and the resistance to deformation and fracture under quasi static and dynamic loading conditions. The studies were performed using specimens in the as received state after high temperature annealing and specimens subjected to equal channel angular pressing at a temperature of 250°C. The anisotropy of strength characteristics of the material after shock compression with respect to the direction of rolling of the original alloy was investigated. It was shown that, in contrast to the quasi static loading conditions, under the shock wave loading conditions, the elastic limit and tensile strength of the magnesium alloy Ma2 1 after equal channel angular pressing decrease as compared to the specimens in the as received state.
