Dynamic Forming of AZ91 Magnesium Alloy Using Explosive Energy

Abstract:

Magnesium alloys are poor in ductility at room temperature and it is known that the cold working is very difficult. Therefore, the development of forming methods, especially at normal temperature, is highly expected [1]. In this paper, AZ91 magnesium block were accelerated more than 100 m/s and the magnesium alloy was well deformed into the die gap. The cross-sectional microstructure was characterized and the deformation of the magnesium was discussed.
