| Abstract: | New sand mold has been adopted to improve the solidification structure of the alloy. The effects of solution treatment and aging treatment on the mechanical properties have been studied by orthogonal and single experiment. The optimum way of heat treatment has been chosen to make the alloy high strength and ductility. |
