Description
Summary:Aluminium hybrid matrix composites (AHMCs) is employed in the automotive and aerospace industries because to their high strength-to-weight ratio, corrosion resistance, and tribological properties. The objective of this research is to examine the metallurgical, mechanical, and corrosion characteristics of Aluminum hybrid matrix composites (AHMCs) produced by reinforcing LM25 alloy with 5% fly ash and varying percentages (4%, 8%, 12%) of TiB 2 using the stir casting technique. The uniform distribution of reinforcing particles was verified by capturing images via SEM and EDAX. Density, Tensile strength, microhardness was conducted for the prepared AHMCs. The outcome reported there was an enhancement by adding reinforcement particles of fly ash and TiB 2 comparing to the pure LM25 alloy. This improvement was attributed to the presence of fly ash and TiB 2 particles, resulting in a higher dislocation density, with increasing TiB 2 content demonstrating improved strength and ductility compared to conventional LM25 alloy.
