| Abstract: | In this paper, the mechanical properties＇ impact factors of a new-type high-strength cast aluminum alloy were analyzed by orthogonal experiments. A best heat treatment process of the new-type high-strength cast aluminum alloy was determined： solution heat treatment with 550 degrees and 16 hours, and aging heat treatment withlSO degrees and 10 hours. In this process, the new-type high-strength cast aluminum was in excellent mechanical properties with tensile strength σb = 498MPa and elongation δ = 6.8%. |
