carbon content. Carbon-partitioning treatment plays an important role in tuning the microstructure and mechanical properties of in situ VCp-reinforced Fe-matrix composite. In this study, the influences of carbon-partitioning temperatures and times on the microstructure, mechanical properties, and wear resistance of in situ VCp-reinforced Fe-matrix composite were investigated. The experimental results......
