Examination of Ductility Increase on Forming of Magnesium Alloy

The major problem for forging of magnesium alloy is the lack of process ductility at the low temperature. The Mg96Zn2Y2 is a high strength magnesium alloy material developed by Mr. Kawamura in Japan. Mg96Zn2Y2, 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 is to examine increasing of ductility of forging process for the Mg96Zn2Y2 material. For this purpose, cylinder upsetting tests 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.
