简介 |
A high-strength, high-toughness cast magnesium alloy and the method thereof, in which the alloy consists substantially of aluminum 3-9 wt%, zinc 3.5-9 wt%, manganese 0.15-1.0 wt%, antimony 0.01-2wt%, and the balance magnesium. The alloy may further comprises a element selected from the group consisting of cerium-riched misch metals, calcium or silicon in 0-2 wt%. In the invention, after the T6 (solution + aging) heat treatment, the mechanical property of the typical alloy of the invention can reach the following requirement : tensile strength s
