Abstract : In the present work, commercially available Nickel Aluminum Bronze (NAB) alloy was composited with CaCO3 through casting route. The developed composite was characterized for microstructure, micro hardness, tensile strength (room temperature and high temperature), and wear rate. The results indicate an improvement in tensile strength by 10%, micro hardness by 2.5 times, and wear resistance by 29% than that of the as-received specimen. This is attributed to the reinforcement of CaCO3 in NAB, which in turn resulted in refinement of the grains, reduction of the β' -phase and preferential formation of intermetallic precipitates of κ-phases (κII, κIII, and κIV).
