| Abstract Scope |
One of the approaches to increase formability of Mg is the use of alloying additions which decrease its stacking fault energy (SFE). Theoretical calculations showed that Sn strongly reduces the SFE of Mg and may facilitate dislocation slip in the basal and non-basal slip systems. Thus, the Mg-6Sn (%wt.) alloy has been investigated in the present study. It was processed by conventional (CR) and differential speed rolling (DSR). Since the DSR method allows to introduce intense shear deformation by controlled differentiation of rotation speeds for upper and lower rolls, it can improve formability of Mg sheets, as compared to conventionally rolled ones, by a significant grain refinement and weakening of texture intensity. The essence of the present study is a comparison of microstructure and mechanical properties of Mg-6Sn alloy processed by CR and DSR using optical and scanning electron microscopy as well as uniaxial tensile tests of miniaturized samples. |
