Research progress of ceramic particles reinforced Al-based composites with micro-nano-scale and high volume fraction

Abstract

Al-based composites reinforced by high volume fraction ceramic particles have attracted much attention because of their high specific strength, high specific modulus, good wear resistance, and low thermal expansion properties. The preparation technology, advantages, and disadvantages of Al-based composites reinforced by high ceramic content are reviewed in this study. The research status of the microstructure and mechanical properties of Al-based composites reinforced by high ceramic particles content is summarized. The effects of ceramic content and preparation technology on the properties of Al-based composites are described. The strengthening mechanism of micro-nano-scale ceramic particles in composites is also expounded. The development trend of micro-nano-scale high content ceramic particle-reinforced Al-based composites is prospected.
