Composite-strengthened heat-resistant and wear-resistant aluminum alloy and preparation method thereof

Abstract

The present disclosure relates to a composite-strengthened heat-resistant and wear-resistant aluminum alloy and a preparation method thereof, and belongs to the field of preparation of high-performance metal materials. In the composite-strengthened heat-resistant and wear-resistant aluminum alloy of the present disclosure, an Al—Si—Cu—Mg alloy is adopted as a matrix, and microalloying elements for improving the heat resistance and a heat-resistant high-entropy alloy (HEA) for improving the wear resistance are added to allow composite strengthening. The preparation method mainly includes the following steps sequentially: smelting and alloying, blowing and refining, blow-compounding, die-casting molding, solution treatment, water quenching, and cryogenic and aging composite heat treatment.
