Abstract

Alumina and Silicon Carbide reinforced LM25 Hybrid nano composite was fabricated by using stir casting method. The LM 25Aluminium is the matrix metal having properties like light weight, high strength and ease of machinability. Alumina which has better wear resistance, high strength, hardness and Silicon carbide which had excellent hardness and fracture toughness were added as reinforcements. The reinforcement was added as 2%, 3% & 5.5% in mass of Alumina along with 2% mass of Silicon Carbide .The influence of Alumina and Silicon Carbide nano particles in the LM 25 matrix studied. The Morphology of composite was related with the properties by conducting such as density test and micro hardness test. The internal structure of the LM 25 metal matrix nano composite was observed using Scanning Electron Microscope (SEM)..
