Abstract

The mechanical properties exposure to heat treatment is examined in this work for AA2219 strengthened by boron carbide (B4C) particles. The content of reinforcement B4C included 2 wt% and 4 wt%. Consistent reinforcing particle distribution was visible in the microstructure and improved strengthening phases. Vickers' hardness increased to 9.67% at 4wt% of B4C and for 2wt% of B4C the hardness was enhanced to 11.24% after the completion of the heat treatment. At a 2 wt% concentration of B4C, UTS grew by 15.16%, and at a 4wt% concentration, it increased by 6.80%. The improvisation has been found in the yield strength of 6.37% at B4C particles containing 4wt% and at 2wt% of B4C particles exhibited 10.32%. Additionally, there had been a drop in ductility of 25.09% and 14.29%, and this implies that strength and ductility compromise. The conclusion of composites' have the potential for high-performance application.
