Abstract

Present research uses SiC, TiO2 and Ni-Gr nanoparticles as supplementary additions to enhance overall machining, and mechanical characteristics of derived LM26 aluminium matrix composites. The bottom pouring type stir casting technique with the two-step feeding method is employed for the development of proposed Composites. Tensile, micro hardness, and impact strength as well as metal removal rate (MRR), Tool wear rate (TWR) of electric discharge machining (EDM) were evaluated to determine the optimal nanoparticle combination that exhibits the best attributes. Results reveal that secondary reinforcements improve the mechanical performance of the samples significantly. At the same HAMC5 exhibits better mechanical, and machining performance and reasonable particle distribution. HAMC5 exhibits 35% higher tensile strength, impact and hardness about 88.3 BHN and 53.8 Joules respectively, which is higher than neat samples
