Fatigue and Facture Behaviour of Al6061-Al₂O₃ Metal Matrix Composite: Effect of Heat Treatment

Abstract

Metal matrix composites of 6061Al - Al2O3 matrix are associated as standard materials inside the space of flying, car and marine applications to move forward the physical properties. Particulates of Al2O3 with 40 µm, 60 µm &100 µm were reinforced utilizing Die casting method. Next stage of fortress is being changed from 0-16wt% in steps of 4wt%. Microstructural characterization has been conducted for the composites to check the homogeneous movement of particles. Fatigue and Facture Toughness properties of 6061Al - Al2O3 composite have been inspected. Effect of fortress on the Disintegration, Shortcoming and Facture toughness properties was considered carefully. A considerable enhancement in Fatigue and Facture Toughness properties was observed by the incorporation of particulates. Formation uniformly dispersed particulates in the matrix was observed for the composite up to 12% filler composition.
