Title:
HIGH-PLASTICITY COMPOSITE MODIFIED ALUMINUM ALLOY PART AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/125282
Kind Code:
A1
Abstract:
Provided are a high-plasticity composite modified aluminum alloy part and a preparation method therefor. The preparation method comprises the following steps: step S1, providing an aluminum alloy melt; step S2, providing a modifier; step S3, adding the modifier into the aluminum alloy melt under an inert gas atmosphere and smelting same to obtain a modified aluminum alloy melt; step S4, performing casting by using the modified aluminum alloy melt to obtain the cast aluminum alloy blank; and S5, performing a heat treatment on the modified aluminum alloy blank, wherein the heat treatment comprises: a solution treatment, involving heating the aluminum alloy blank to 530ºC-550ºC, and maintaining the temperature for 120-300 min; a water quenching treatment, involving adding the aluminum alloy blank after the solution treatment into a water bath with the temperature of 60ºC-70ºC, and water quenching same for 2-4 min; an aging treatment, involving maintaining the aluminum alloy blank after the water quenching treatment at 110ºC-140ºC for 120-240 min, then further raising the temperature to 160ºC-200ºC and maintaining the temperature for 20-60 min, and then cooling to room temperature to obtain the high-plasticity composite modified aluminum alloy part.
