Forging of Discontinuously Reinforced Aluminum Composites

Abstract

DISCONTINUOUSLY REINFORCED aluminum (DRA) alloy metal-matrix composites (MMCs) represent an advanced aluminum materials concept whereby ceramic particles, or whiskers, are added to aluminum-base alloys through the use of either ingot-melting or casting and/or powder-metallurgy (P/M) techniques. In these materials systems, the reinforcing material (for example, silicon carbide, boron carbide, or boron nitride) is not continuous, but consists of discrete particles within the aluminum alloy matrix.
