Abstract
Magnesium alloy AZ31 metal sheets were formed at room temperature with a pulsed
magnetic field induced by a flat coil. For this a die with variable die radius and inside
diameter was used. The forming results were evaluated regarding to deformation, die
radius, inside diameter, micro hardness, texture examination of forming area and energy
input. In addition high velocity forming process was compared to a quasi-static forming
process at room temperature. Therefore an experimental setup with an adapted punch
was constructed. Punch geometry was defined in dependence of the high velocity forming
structure of a sample at well-defined energy input. By comparing texture and micro
hardness at forming area a distinction of high-speed forming process and quasi-static
process is determined.
