文摘

The present study aims at development of light weight, high strength Mg–2%Zn/Al and Mg–2%Zn/anodized Al based multilayered composite by the accumulative roll bonding (ARB) process. The ultrafine grained multilayer composite was successfully roll bonded by using binary Mg–2%Zn alloy, pure aluminium and anodized aluminium at 300 °C with 50% reduction up to 5 passes. Multilayered composites are characterized with respect to microstructure, mechanical properties. Density of the ARB processed Mg–Zn/Al multilayered composites have been found to be 21% reduction of weight as compare to pure Al. The composite with anodized Al showed better tensile strength and microhardness as compare to Mg–Zn/Al multilayered composites.
