Study of Effect of Hot Forging on Microstructure and Mechanical Properties of Al-SiC+3 Wt.% AL2O3 Hybrid Composites.

Particle reinforced MMC succeeds in developing the metallic matrix with ceramic particle reinforcements to result in improved strength, mainly at elevated temperatures but adversely affects the ductility of the matrix. The present study aims to disperse different weight % (3,6,9) of SiC and 3wt.% Al2O3 particles in aluminum melt and fabricated composite. The evolution of microstructure and morphology of composite are studied using FESEM, Optical Microscopy, EDAX and deformation characteristics of Al-SiC+Al2O3 composite at cold conditions was studied. Cast nd forged composite material was subjected to hardness test and tensile test. The results show that hardness and strength of fabricated Al-SiC composite improves and ductility declines as compared to Al alloy in both as-cast and hot forged conditions. [ABSTRACT FROM AUTHOR]
