Physical and mechanical properties of stir-casting processed AA2024/B₄Cp composites

In this study, metal matrix composites of an aluminum alloy (AA2024) and B 4 C particles with volume fractions 3, 5, 7, and 10 vol% and with sizes 29 and 71 μm were produced using stir-casting technique. The effects of B 4 C particle content and size of boron carbide on the mechanical properties of the composites such as hardness, 0.2% yield strength, tensile strength, and fracture were investigated. Furthermore, the relation between particle...
