摘要

The present research examines the mechanical behavior and microstructural features of aluminum matrix composites containing Silicon Carbide (SiC) and boron carbide (B₄C) as reinforcing particles. The matrix material used is LM25 alloy with different SiC percentages (4–12%). Whereas a fixed weight percentage of 2 wt% B4C is added. The composites are manufactures by stir casting method. Particle distribution in the composite is analyzed by microstructure studies. Tensile strength and hardness of the developed composites are studied. Results reveal a substantial enhancement of mechanical properties by SiC particle addition to the aluminum matrix.
