An ultra-hard aluminum-based high-entropy alloy mainly composed of recycled aluminum and a preparation method thereof
By using recycled aluminum as the main material, introducing Si, Mn, Mg, and Fe elements, and carrying out arc melting and heat treatment, a high-entropy aluminum-based alloy with excellent comprehensive performance was prepared. This solved the problems of insufficient hardness and toughness in the existing technology, improved the corrosion resistance of the alloy, and reduced the cost.

Abstract
The application discloses a super-hard aluminum-based high-entropy alloy taking recycled aluminum as a main material and a preparation method thereof. x Ti y V z Zr w Nb n weighing; wherein M is the recycled aluminum alloy, x+y+z+w+n=1, x=0.5-0.6, y=0.15-0.3, z=0.03-0.07, w=0.1-0.2, and n=0.03-0.07; the recycled aluminum alloy contains 0.2-8wt% of Si, 0.2-6wt% of Mg, 0.1-0.6wt of Mn, 0.1-0.4wt of Fe, and the content of Al is greater than or equal to 90wt%; firstly, the TiVZrNb alloy is prepared, then the recycled aluminum alloy is smelted, and after heat treatment, the super-hard aluminum-based high-entropy alloy is obtained. The application greatly improves the hardness of the aluminum-based high-entropy alloy while having good toughness and corrosion resistance.
