title = "Microstructural investigation of twins under the fracture surface in AZ31 magnesium alloys",
abstract = "The present work was aimed at understanding the fracture behavior and mechanism of magnesium alloys. AZ31 magnesium alloys were deformed to failure by tensile loading at room temperature. The underlying microstructure of the fracture surface was investigated with a focused ion beam (FIB) microscope and a transmission electron microscope (TEM). The microscopic feature of the fracture surface could be classified by its morphology into three types: (1) dimples, (2) elliptic facets, and (3) severely sheared dimples. Observation of the substructure with TEM indicated the presence of {10-12} twins under the elliptic facets and the presence of {10-11}-{10-12} double twins under the severely sheared dimples. These results suggest that the localized shear deformation in the double twin become a crack initiation site. Failure occurs by the propagation of the crack along the interface of the {10-12} twins to form the elliptic faces and within grains to form the dimple feature.",
