To examine the microstructure and wear behaviour of the composite material Making aluminum-boron carbide composites is necessary due to the growing need for lightweight materials in emerging industrial applications. In this case, aluminium alloy-boron carbide composites with different particle weight fractions were produced using liquid metallurgical procedures. Due to its extreme hardness (it is the second-hardest material after diamond), (5.3 Mpa.m1/2, density 3.5g/cm3) and boron nitride (melt.pt: 29730C, density 3.45g/cm3)), boron carbide (fracture toughness 3.5 Mpa.m1/2) is a ceramic material that could be an alternative to SiC (melt.pt: 27300C, density 3.21g/cm3).High strength (melt point: 27630C, boiling point: 35000C), The desirable properties of boron carbide are low density (2.52 g/cm3), extremely high hardness, exceptional wear resistance, and strong chemical stability. Composites with low density are becoming more and more popular. © 2024 Elsevier B.V., All rights reserved.
