P/M aluminum matrix composites: an overview

This paper reviews the state of art concerning powder metallurgy (P/M) aluminum matrix composites. Among all the metal matrix composites (MMCs) aluminum could be the most widely used metal as matrix due to its low density coupled with high stiffness. There are different manufacturing methods which can be applied for this composite. From these, P/M could be remarked as a highly effective and economic method compared with other alternatives.
