The paper presents the results of a study of the effect of the texture of a magnesium specimen on the mechanical properties of its plates and foils. Three cylindrical specimens with different columnar structure orientation were used for the experiments. The deformation was carried out in two steps at room temperature. First, long magnesium plates 1 mm thick (true deformation e ~ 3.9) were produced by lateral extrusion. These plates were then deformed by rolling to obtain foils, 120 μm thick (e ~ 6.0) and 10 μm thick (e ~ 7.5). It was seen that the sharpness of the basal texture and mechanical properties depend on the orientation of the initial samples. It has been shown that the deformation leads to a significant grain refinement: from several millimeters to several microns. This is due to the simultaneous development of slip, twinning, and dynamic recrystallization processes.
