摘要
In this paper, a rheo-diecasting process of AZ91D alloy semi-solid slurry produced with a twin-screw stirring mixer was investigated. The results show that the tensile strength and elongation of the sample made by rheo-diecasting were 37% and 44% higher, respectively, than those produced by conventional liquid diecasting. The castings fabricated by rheo-diecasting possessed good density with low shrinkage and could be heat treated. It is a "near-net shape" production process.
