Mechanical and Wear Behaviour of Al60601- Al2o3 composites and AL6061-Al2o3-Gr Hybrid Composites

Abstract

Increase in the performance requirements of materials for aerospace and automobile applications has led to the development of numerous structural composite materials. Some of these composites are particle-reinforced metals-matrix composites, ceramic particle reinforced composites. These composites by virtue of their higher specific strength and stiffness, improved elevated performance, have become important and necessary materials used in various industrial applications. Therefore the mechanical properties of these composites have received much attention. Some of the techniques used for the development of these composites are stir casting, powder metallurgy and squeeze-casting. In this paper we made an attempt to study the mechanical and wear behaviour of Al alloy composites containing various al2o3 compositions namely 3%, 6% and 9% by weight, were fabricated and tested, and their properties were compared with Al alloy hybrid composites containing 2 wt% Graphite constant and various al2o3 compositions namely 3%, 6% and 9% by weight.
