Research progress on particle-reinforced titanium matrix composites prepared by powder metallurgy method

Particle-reinforced titanium-based composites are widely used in aerospace, automotive, and medical engineering due to their high strength, light weight, corrosion resistance, and excellent high temperature mechanical properties. The development overview and research results of titanium-based composites in domestic and international were introduced in this paper. The matrix composition of titanium-based composites, the morphology and physical properties of particle reinforcement materials, the introduction method of reinforcement, the preparation process, and the mechanical properties of the composites were described. Especially, the process characteristics and material properties of the particle-reinforced titanium-based composites prepared by the different powder metallurgy methods were discussed, and the propose prospects for the further research on titanium-based composites were expected.
