Hot tensile tests are employed herein to explore the microstructural evolution and fracture damage of a hot-extruded Mg-9.1Y-1.8Zn (wt%) alloy at deformation temperatures of 250-400 degrees C and strain rates of 0.005-0.1 s(-1). The deformed microstructure and fracture morphology are systematically studied using electron backscatter diffraction (EBSD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The flow stress tends to decline with increasing tensile temperature or decreasing strain rate. Under all the tested conditions, discontinuous dynamic recrystallizat...
