Abstract

Compressive tests were performed to homogenized AZ31 magnesium alloy samples to various strains and fracture at room temperature (RT). The microstructure of the samples was observed by optical microscope(OM); the twin types were examined by electron backscattered diffraction (EBSD) technique; and the fracture surfaces were detected by scanning electron microscope (SEM). The fracture mechanism was discussed by considering the interaction among basal slip, twinning and interface motion. It was considered that basal slip and {10 2} twinning work together during deformation. Basal slip may result in the potential origin of fracture at grain boundaries (GBs); while the interface of {10 2} twins may become the favorable source of fracture across the grains.
