英文摘要	The effects of mould temperature on microstructure and tensile properties of thixoforged in-situ Mg2Sip/AM60B composites have been investigated. The results indicate that the mould temperature affects the secondary solidification behavior and thus the compactness of the secondary solidified structures, solubility of Al in alpha-Mg particles, beta phase size and amount, plastic deformation and recrystallization during thixoforging through changing solidification rate, and finally the tensile properties. Correspondingly, the fracture mode also changes with the temperature. In comparison with thixoforged AM60B alloy, the UTS of thixoforged composite increases 35.6% due to the reinforcement of Mg2Si particles. The strengthening mechanism of Mg2Si particles is an additive or synergetic effect combining the load transfer mechanism, the Orowan looping mechanism and dislocation strengthening mechanism.
