The major problem for forging of magnesium alloy is the lack of process ductility at the low temperature. The Mg_<96>Zn_2Y_2 is a high strength magnesium alloy material developed by Mr. Kawamura in Japan. Mg_<96>Zn_2Y_2, a newly developed high strength magnesium alloy material is expected as forged parts of the automobile and materials for aerospace applications. It is necessary to clarify forging process characteristics of this material. The purpose of the present study examined increasing of ductility of forging process for the Mg_<96>Zn_2Y_2 material. For this purpose, cylinder upsetting tests of were performed by this method of two stages. In addition, the deformation resistance and ductility of the material were examined. The two stages forging process is effective for an increase of ductility of the material.
