| Popis: | Casting properties and process improvement of A356 aluminium alloy which is used to cast automobile engine cylinder is investigated in the present paper. The effects of flow field and temperature field on the microstructure and defects distribution of A356 is analyzed by ProCAST software. Simutaneously, the mold filling and solidification of the bottom gating and rotated solidification technology is simulated. Thus, the optimize process parameters obtained by calculating is pouring temperature 725°C, pouring times 21s, and preheating temperature of cylinder sleeve 450°C. Then, the cylinder is made under the condition of above parameters and the microstructure of the cylinder was observed. The results show that the microstructure and defects distribution which is simulated by ProCAST software are good agree with the experiments.
