Hybrid Metal Matrix Composites (HMMC) enhances the main properties like hardness, tensile strength as well as it saves weight. Reinforced Hybrid metal matrix composites attracts because it enhances mechanical properties. Many researches are going on in material science field to enhance the mechanical properties of the materials and improve the quality of the material. Present research work carried out to fabricate the SiO2 and Al2O3 reinforced Nickel based alloy. Reinforcement is added in matrix with 9% in weight SiO2 (Constant) and varying 3% to 12% in weight Al2O3 in steps of 3% in weight. Induction furnace is used to melt the composites, then the composites are machined and tested after casting. Evaluation of microstructure, tensile strength and micro hardness of hybrid metal matrix (Monel M- 35+SiO2+ Al2O3) is done and analyzed.
