• Mg-Sn alloy
• high temperature deformation
• ductility

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 Mg(2)Sn particles in the alpha-Mg matrix, for example, 184 % at 350 A degrees C under a strain rate of 1 x 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 x 10(-3) s(-1). Such an improvement in ductility is due to the significantly refined grain structure that results from the addition of Zn.
