Abstract
Engineering fraternity is searching for new materials which possess higher strength and lower weight materials. In this connection Aluminium metal matrix Composites are the very constructive light weight materials of universal engineering applications with enriched mechanical characteristics and are promising for Naval, aerospace and automobile applications. However, in various applications, mechanical properties such as hardness and tensile strength are prerequisite and are more relative to the closer surface regions. In other hand one of the surface treatments, Laser peening is an advanced surface treatment technique, to improve the surface morphology and hence the mechanical characteristics such as tensile strength and Hardness and is an added advantage for various applications. In the present work aluminium metal matrix composites are fabricated by reinforcing 7.5% SiC in Al6082 via stir casting method and surface of the AMMCs are laser peened using a 2.5 J flash lamp pumped Electro–Optically (E–O) Q-switched Nd:YAG laser system and Hardness and tensile behaviour are studied and Hardness and tensile strength are improved with increase of laser power density from 1J to 2.5J
