Mechanical Properties of AA7075- nano-B4C Metal Matrix Composites Prepared by Powder Metallurgy

Abstract

Powder metallurgy prepared composites are preferred over composites made of other liquid manufacturing techniques, due to its unique advantages such as near-net shape. Metal matrix composites with reinforcement in its nano size exhibit enhanced Mechanical properties. In the present work, the effect of nano -B₄C over the Mechanicalproperties of AA 7075composites is elaborated. The nanocomposites produced by powder metallurgy were tested for hardness, compression, and density. The results obtained exhibits increased compression strength, density and hardness of composites in comparison with the micro reinforcement.
