Abstract
Thin-walled aluminum alloy shell was prepared by squeezing casting in a special mould. The effects of preheated temperature of mould, pouring temperature, pressure and holding pressure time on deformation of the components were expounded, meanwhile, the tensile properties, microstructure and fracture morphology of the components were observed. The results show that increasing temperature is favorable for the filling of the liquid aluminum alloy, and the optimized pouring temperature is 720 ~ 740 °C. The plasticity and strength of the components poured at 720 °C~40°C can meet the requirements, and the microstructure of the components exhibits fine grain size and dendrite-absence as well as tough fracture features.
