The isothermal forging of a cast Mg-5.89 wt.% Zn-0.79 wt.% Y-0.32 wt.% Zr magnesium alloy was carried out to form the tank cover. The forming process of isothermal forming is studied by finite element model simulation and experiment. Based on the optimum isothermal forging process, the isothermal forging experiments of the cast Mg–Zn–Y–Zr magnesium alloy tank cover were successfully conducted. The...
Energy saving and improving product performance are long-term concerns in extrusion process. Therefore, this paper proposes a novel extrusion process called alternate extrusion (AE). The proposed process uses split punches alternately instead of the overall structure to apply the downward load, but receives an unexpected load-saving and grain refinement effect. Experimental and finite element method...
