Effect of red mud on microstructures and tensile properties of M142 eutectic aluminum-silicon alloy

Abstract This study examined the impact of incorporating varying quantities of red mud (a primary by-product of the aluminum industry) on the microstructure and tensile properties of the M142 eutectic aluminum-silicon alloy. Researchers utilized red mud as a raw material, initially applying chemical deposition nickel coating technology before integrating it into the M142 eutectic aluminum-silicon alloy produced through gravity casting. The experimental results indicated that red mud notably impr
