by the spray forming process, and its microstructure evolution during the semisolid reheating process was investigated. The results show that, the primary Si phase coarsens during the reheating process... a densification process before application. Conventional forming methods [7,8], such as extrusion and roll, were used to densify the spray-formed materials. However, the plastic deformation of Al-Si alloys......
