This research mainly investigated the processing temperature and the processing speed influence upon the deformation resistance and ductility of three kinds of casting magnesium alloy materials, one of which was named Mg_<96>Zn_2Y_2, a kind of high-strength magnesium alloys. For this purpose, compression deformation experiments of column were performed. We also examined and compared the variation of deformation resistance and ductility of three kinds of materials. Furthermore, the dependence on deformation temperature and deformation speed of these materials was evaluated.
