A Comparative Study of Mechanical Properties, Thermal Conductivity, Residual Stresses, and Wear Resistance of Aluminum-Alumina Composites Obtained by Squeeze Casting and Powder Metallurgy

Abstract Squeeze casting and powder metallurgy techniques were employed to fabricate AlSi12/Al 2 O 3 composites, which are lightweight structural materials with potential applications in the automotive industry. The impact of processing route on material properties was studied. Comparative analyses conducted for Vickers hardness, flexural strength, fracture toughness, thermal conductivity, residual stresses, frictional wear. Our results show that squeeze cast composite exhibits superior those obtained using metallurgy.
