W-NbC composites with up to 40vol% NbC were prepared by hot-pressing at 2200°C under a pressure of 30MPa. The effects of NbC content on the microstructure and mechanical properties of the W-NbC composites were investigated. A (Nb, W)C solid solution was detected at the NbC/W interface, and W2C phase formed in the composites. A core/shell structure was found in the composites as the NbC content is...
