Magnesium alloy is the lightest in a practical metal and that expected to be used various industries. However, the magnesium alloys has the property that with the plastic forming at ordinary temperature range is difficult since film aggregate texture is formed. It is understood that RCP refine grains and reduce crystalline orientation. The extruded magnesium alloy via casting has anisotropy; the mechanical property is different according to extruding direction. It is suitable that the anisotropy is smaller when magnesium alloys are used at various industrially. In this study, the anisotropy for extrusion direction of the extruded AZ31 magnesium alloy via rollcompaction process is investigated, and influence of microstructure and texture on anisotropy is cleared.
