The microstructure and mechanical responses of the AZ31 with the addition of 1.8% Sn alloys have been studied and compared. Mg alloy sheets were prepared with metal model casting method and subsequent processes by conventional extrusion (CE) and differential speed extrusion (DSE). Mg alloys were hot extruded at 400oC with the extrusion ratio of 101:1. The microstructure of Mg alloy sheets was examined by optical microscopy (OM) and scanning electron microscope (SEM). The results indicated that the grains were dynamically recrystallized after the extrusion process. Moreover, DSE process dramatically enhanced the room temperature ductility of the extruded sheets. It was also presented that the Mg alloy processed by DSE exhibite a classical dimple structure as a result of slip accumulation and ductile tear.

Modern wrought magnesium alloys have poor formability at room temperature, which impedes the wider uptake of these alloys by the industry. Over the last decades, research activities in the area of magnesium alloy development have grown enormously and have produced a pallet of exciting findings, which the authors summarize in this concise review focused on the effect of the microstructure, primarily of grain size, on room temperature ductility of wrought Mg-based alloys. Well-established paths and modern strategies to control over the grain size distribution are discussed. It is demonstrated that the use of severe plastic deformation techniques for ultimate grain refinement in magnesium alloys opens new windows for improving their mechanical properties profile by managing both strength and ductility in a wide range. However, it is shown that grain size alone cannot be regarded as a key parameter controlling the mechanical behavior of Mg alloys. The effect of texture is of paramount importance for the overall mechanical response of Mg alloys and this may supersede the influence of grain size.
