Abstract：

Microstructure evolution of semi-solid SiCp/AZ61 composites with different deformation temperatures,strain rates,volume fractions of SiCp and deformation degree during compression process was investigated.The results show that friction coefficient is decreased and the possibility of solid particles or aggregates slipping and rotating will increase with the temperature increase.The liquid phase during low strain rate distributes around the matrix with the strain rate decrease.The grain size decreases obviously with the deformation increase.
