Abstract In-situ synthesized ceramic particles have the advantages of small size, regular shape, high stiffness and clean interface of particle/matrix. It is an important technique to prepare high-performance aluminum matrix composites. In-situ TiB2 particles reinforced Al matrix composites exhibit high strength, stiffness, good ductility, fatigue and machining properties. In addition, the components can be manufactured from the in-situ synthesized composites by liquid forming, plastic working and additive manufacturing. It avoids the common problems of Al matrix composite, such as, high cost, complex processes, difficulty in machining processes and hard to fabricate large sized and/or complex components. Therefore, in-situ TiB2 particles reinforced Al matrix composites have a broad application prospect. Based on the detailed cases, the advantages of fabrication and comprehensive mechanical properties of in-situ TiB2 particle reinforced Al matrix composites were analyzed. The application and development in future of the composites are forecasted.
