Abstract
Disclosed are a rolled (FeCoNiCrRn/Al)-2024Al composite panel and a preparation method therefor. The preparation method involves taking pure aluminum as a matrix, adding an FeCoNiCrRn medium-entropy alloy with a high strength and toughness as an reinforcing phase to prepare an FeCoNiCrRn/Al composite material, then laminating the FeCoNiCrRn/Al composite material with aluminum alloy 2024, and preparing the (FeCoNiCrRn/Al)-2024Al composite board by means of hot-rolling recombination, which solves the problem that high-strength aluminum matrix composites (AMCs) are prone to instantaneous breakability and low ductility, thereby improving the overall performance of the material. The present disclosure adopts microwave sintering (MWS) to fabricate a medium-entropy alloy-reinforced AMC, and adopts hot-roll bonding to fabricate the (FeCoNiCrRn/Al)-2024Al metal composite panel. The composite panel fabricated by the present disclosure has excellent comprehensive mechanical properties, and has high application values for promoting the application of modern lightweight and high-efficiency industrial materials in aerospace, new energy vehicles, and the like.
