Isothermal Precision forging of magnesium alloy components with high performance

Abstract Because of hexagonal crystal structure, magnesium alloys, especially magnesium alloys with addition of rare earths, exhibit poor formability at room temperature. The isothermal precision forging process at elevated temperature can improve the formability of magnesium alloys. In this paper, the isothermal precision forging process of the complex shape case of Mg-Gd-Y-Zn-Zr magnesium alloy was simulated based on FORGE Nxt. A two-stage isothermal precision forging process was determined. According to the simulation results, isothermal precision forging experiments of magnesium parts with high performance and complex shape were successfully carried out. After isothermal precision forging process, the cases of magnesium alloy were subjected to heat treatment. Moreover, the mechanical properties of parts were also determined.
