主　　题：Magnesium alloys Microstructure evolution Texture Anisotropy 

摘      要：The formability of magnesium alloys at ambient temperature can be enhanced by alloying additions such as Ca and RE elements,which is ascribed to the weakened basal *** produce magnesium alloy sheets with excellent comprehensive performance,the evolution of texture characterization during fabrication process and subsequent effect of texture on mechanical properties are vital controlling *** this investigation,three experimental Mg-3Al series alloys were hot rolled and annealed to sheets with 1 mm *** microstructure evolution during rolling and annealing process was ***,the influence of texture on tensile properties along different tensile directions was also *** results show that weakened basal texture and refined grains were achieved with the co-addition of Ca and RE ***,strengthening of mechanical properties wasn t *** hot rolling process,microstructure was refined,second phase particles broken,and basal texture was *** basal texture was weakened during annealing *** behavior influenced by formation of second phase was dominated to attenuate basal *** deformation behavior was controlled by basal slip and followed Schmid factor ***,the weakened basal texture and activation of non-basal slips during hot rolling process can contribute to diminish the anisotropy of tensile properties.
