Abstract
In the present study, we have investigated the high temperature deformation behavior of Mg-Sn(-Zn) based alloy systems in comparison with that of Mg-Al alloy. Compared with Mg-Al alloy, Mg-Sn alloy exhibits significantly refined grain structure and high ductility due to the presence of fine Mg2Sn particles in the α-Mg matrix, for example, 184 % at 350 °C under a strain rate of 1 × 10−3 s−1. When Zn is added to the Mg-Sn alloy, the elongation to failure remarkably increases from 184 % (Mg-Sn alloy) to 310 % under a strain rate of 1 × 10−3 s−1. Such an improvement in ductility is due to the significantly refined grain structure that results from the addition of Zn.
