Abstract

This study focuses on investigating the tensile mechanical properties and failures of the α + β two-phase Mg-10.3Li-2.4Al-0.7Zn (wt.%) alloy at testing temperatures from -25 to 250 °C. The tensile stresses and elongations are sensitive to the deformation temperatures. A significant ductile-to-brittle transition temperature is recognized at about 50 °C. The failures, which occurred from brittle fracture with evident cleavage to ductile dimpled ruptures, is related to the transition of slip systems with increasing temperatures and the cavitation between α/β-phase interface.
