Document Type and Number:
WIPO Patent Application WO/2023/125266
Kind Code:
A1
Abstract:
The present invention provides a high-plasticity aluminum alloy part and a manufacturing method therefor. The manufacturing method comprises the following steps: S1, providing a cast aluminum alloy billet; and S2, carrying out heat treatment on the aluminum alloy billet, wherein the heat treatment comprises: solution treatment: heating the aluminum alloy billet to 530-550°C, and carrying out heat preservation for 120-300 minutes; quenching treatment: adding the aluminum alloy billet subjected to solution treatment into a water bath having a temperature of 60-70°C, and carrying out quenching for 2-4 minutes; aging treatment: performing heat preservation on the aluminum alloy billet subjected to quenching treatment for 120-240 minutes at a temperature of 110-140°C, further heating to 160-200°C, keeping the temperature for 20-60 minutes, and cooling to room temperature to obtain the high-plasticity aluminum alloy part. According to the preparation method for a high-plasticity aluminum alloy part in the embodiments of the present invention, by carrying out specific heat treatment on a casting part, the mechanical strength and ductility of the casting part can be greatly improved, the requirements of aviation, aerospace and automobile fields, etc. are satisfied, and moreover, the impact resistance of a high-plasticity aluminum alloy part is improved.
