英文摘要	The mechanical behaviors of the thixoforged in situ Mg2Sip/AM60B composite at elevated temperatures were evaluated. The results indicated that the thixoforged composite exhibits higher UTS (ultimate tensile strength) than that of the thixoforged AM60B at the cost of elongation. As the testing temperature rises from 25 to 300 degrees C, the UTS of both these two materials decreases while their elongations increases. The enhanced dislocation motion ability, the softened eutectic phase at 120 degrees C, the activated non-basal slipping and the dynamic recovery and recrystallization mechanisms at 150 degrees C are responsible for the change in tensile properties with testing temperatures. The fracture mode transforms from the ductile into the brittle as the initial strain rate increases from 0.01 to 0.2 s(-1) at 200 degrees C.
