Research and prospect of particle reinforced iron matrix composites

Particle reinforced iron matrix composite (PRFMC) have attracted widespread attention because of their good physical and mechanical properties. In this paper, the preparation technology of PRFMC, the influence of particles on the mechanical properties of iron matrix composites (FMC) and the reinforcement mechanism are systematically reviewed. The results show that the preparation technology has a significant impact on the physical and mechanical properties of PRFMC. The defects in the traditional preparation technology are improved in the new preparation technology. The addition of reinforcing particles has a great influence on the mechanical properties of FMC, and the strengthening effect varies according to different reinforcing particles. The reinforcing mechanism of PRFMC mainly includes microstructure strengthening and micromechanical strengthening.
