Processing and strengthening mechanisms of boron-carbide-reinforced aluminum matrix composites

Boron-carbide-reinforced aluminum matrix composites are widely used as various function materials. This paper aims at reviewing theoretical and experimental background related to boron-carbide-reinforced aluminum matrix composites. The powder milling processing, solid sintering, thermo-mechanical processing and the effects of reinforcement particle size on the microstructure and morphology evolution of the aluminum matrix composites are reviewed. The formation of interface between boron carbide and matrix and strengthening mechanisms of the boron-carbide-reinforced aluminum matrix composites are discussed.
