Fabrication, Microstructure, and Properties of In Situ V2C-Reinforced Copper Composites

In this paper, in situ V2C-reinforced Cu composites were successfully fabricated by hot pressing at 750 °C under 25 MPa using Cu and V2SnC powders. Due to decomposition of V2SnC to V2C and Sn during sintering...
