This study investigated the metal forming of magnesium alloy plates using dynamic load, which is referred to as explosive forming. Cold metal working is difficult to perform on magnesium alloys using typical metal forming methods. Therefore, this study used explosive forming technique with a convex die. This is one of the metal forming technologies equipped with a special forming mechanism. The desired forming result was obtained by controlling the pressure wave applied to plates when the inclination of the die was steep, that is, the amount of deformation was large. In addition, the control of the pressure wave was investigated through numerical simulation.
