Development of Al-Cu Metal Matrix Composite through Hot Compaction

Metal Matrix Composites significantly enhanced mechanical properties- like higher stiffness, strength& light in weight. Development, Hardness and microstructure were carried out on hot forged and annealed treated Al4.2 %Cu metal matrix composites to understand their fabrication process and their mechanical properties. Al4.2 %Cu was prepared by warm forging using suitable die assembly on a 150 ton capacity hydraulic press. The Al4.2 %Cu powder was well blended in the container and then they are poured into the Die assembly at three different temperatures- 400C, 450C and 500C to make the three different samples successfully. All the three developed samples are cut into two halves, the one half as the forged part and the other half for annealed treated. This paper captures the salient features of development, hardness and microstructure of Al4.2 %Cu Metal Matrix Composites.
