Abstract

A relationship between microstructure and strain induced by different plastic working is investigated in AZ31 magnesium alloy. AZ31 magnesium alloy was processed by different plastic workings (forging, rolling, extrusion, equal-channel angular pressing (ECAP), caliber rolling) at 573 K with equivalent strain controlled to the similar value. The strain induced in the processes was computed by using the finite element method (FEM). The deformation texture of forging and rolling were intensive basal texture, but the texture of extrusion, ECAP and caliber rolling were relatively weak. The FEM calculation and deformed texture showed that in all five processes, the basal plane is oriented to the direction perpendicular to compression strain, and tendency that the more compression strain is induced, the more intensive basal texture is formed.
