The Study of A356 Alloy Rheo-Squeeze Casting Process
2016
In this paper, the castings of A356 alloy were made by the rheo-squeeze casting with slurry-making from the process of LSPSF. Experiments were designed to study the influence of three parameters in rheo-squeeze casting process, such as injection speed, mould preheating temperature and injection pressure, on castings performance. The results show that high-quality castings were produced with the injection speed of 0.5m/s ,the mould preheating temperature of 240°C, the injection pressure of 50MPa. The mechanical properties, such as the yield strength, tensile strength and elongation of the castings with T6 heat treatment are 241 MPa, 328MPa and 11.6%, respectively.
