Study of a Fine-Grained AZ31 Magnesium Alloy Prepared by Equal Channel Angular Pressing
A fine-grained magnesium alloy AZ31was obtained through equal channel angular pressing (ECAP).Mechanical properties and the microstructures after deformation under tension and compression were investigated. The tensile strength, compressive strength and the elongation to failure of the fine-grained AZ31 are enhanced due to the reduction of grain size. The compressive ultimate strain (CUS) of the fine-grained AZ31 magnesium alloy is lower than that of the initial state due to the formation of shear bands during compression. The ECAP processed AZ31 magnesium alloy exhibited no tension/compression asymmetry in yielding.
