Experimental study of strength and deformation properties of the magnesium alloy MA14-T1, depending on the type of stress-strain state, the type of cutting the samples with respect to the rolling direction, strain rate and temperature. The static and dynamic stressstrain curves were obtained at different loading conditions and temperatures. It were determined the strength properties as well as their dependence on the strain rate and temperature. It is marked the substantial change in the course of the deformation diagram of samples with a longitudinal direction of cutting after the deformation ~6 %.
