Abstract

With the booming development of new energy vehicles, integrated die casting has become an important means of automotive parts manufacturing, and there is an urgent need for age-free heat-treated aluminium alloys in the industry. Therefore, a new ageing-free heat-treated aluminium alloy was developed to analyses the difference in mechanical properties before and after heat treatment and its mechanism. When the new aluminium alloy is not aged, the tensile strength is 278.78MPa, which is 92.2% of that after aging; the yield strength is 122.65MPa, which is 64.39% of that after aging; and the elongation rate is 8.89% which is 126.8% of that after aging, which meets the needs of application. The reason for the excellent performance of the new aluminium alloy is that the new aluminium alloy can precipitate enhanced phase Mg2Si, α2-Al phase and eutectic Si without aging treatment.
