Abstract

The contemporary investigation deals with the formation of Al2024 composites reinforced with boron carbide particulates by varying wt.% (1, 3, and 5%) routed through a liquid metallurgical process. The 3 different mesh sizes say 100, 200, and 300 of B4C particulates have been chosen as reinforcement. Heat treatment has been done for the machined test specimen to know the effect on UTS and compression strength for the formed composites. UTS and compression strength have been evaluated for both Al2024 alloy and Al2024/B4C composites with and without heat treatment conditions. The density of the formed composite material is decreased when the content of reinforcement increases in the Al2024 matrix. The result of this investigation revealed that as wt.% of B4C increased there is a significant increase in the UTS and compression strength, accompanied by a reduction in its ductility. Fracture analysis has been done for the tensile fracture specimen to know the bonding between matrix and reinforcement and type of fracture. Further, an attempt is made to validate experimental results by using regression analysis through Minitab software.
