Evaluation Of Mechanical Properties In AA2219-B4C Composites Produced By Stir Casting And Age Hardening

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.
