150001, China) Abstract:The thixoforming in pseudo-semi-solid state based on the semi-solid metal forming was proposed. The microstructure of the prepared Al/Al2O3 composite cup shell was observed by SEM, and bend strength and fracture toughness of this alloy were measured. The results show that the cup shell is of three-dimensional network structure and closely bounded interfaces. The bend strength......
