Objective of the present work focus to study the effect of hot forging on high temperature tribilogical properties of aluminium composite reinforced with agro and industrial waste, i.e. fly ash and Rice husk ash. The developed MMCs are hot forged at a temp of 450C with a reduction of 80% in different step. The as cast and forged alloy and its composite are subjected to microstuctural analysis and wear test. Microstuctural analysis shows uniform distribution of the particulate in the matrix alloy. After forging reinforcement RHA and FA are united towards the material flow direction throughout hot forging. During hot forging, the effect of plastic deformation and high temperature lead to recrystalization of Al6061/RHA and Al6061/FA MMCs with grain refinement. Refinement of grain enhanced the mechanical strength. The worn out surfaces are seen by SEM to know the mechanism of wear. Forged composite possesses lower wear rate under all the condition compared with as cast alloy and composite. Hot forged Al6061 alloy reinforced with fly ash composite gives least wear rate at 150 C in comparison with its room temperature.
