Abstract

This article reviews the tensile properties and toughness characteristics of discontinuously reinforced aluminum (DRA) composites in terms of particle spacing, particle size, volume fraction, matrix alloy, and matrix microstructure. Both fracture toughness data and impact toughness data of the DRA composites are summarized. The article discusses the effects of confining pressure on the ductility of the DRA materials. It describes the fatigue behavior, such as stress-life behavior, strain-life behavior, and fatigue crack propagation, of the DRA.
