The proposed work investigates the effect of micro-particle reinforcement of Niobium Carbide (NbC) and Molybdenum disulphide (MoS 2 ) with AL7475 alloy. Mechanical properties, including fracture toughness and Brinell hardness, are studied for the composites AL7575-Nbc and AL7575-MoS2. The preparation of aluminium metal matrix composites is done by using the liquid metallurgical technique by varying the weight percentage (wt%) of Niobium Carbide (NbC) and Molybdenum disulphide (MoS2 ) from 2 to 10%. The reinforcement compounds are analyzed using Scanning Electron Microscope. The fracture toughness and Brinell hardness are determined using ASTM E10 and ASTM E23 standards, respectively. The Brinell hardness of the composites increased with reinforcement compounds, whereas the fracture toughness decreased with an increase in NbC and MoS 2 .
