Advanced W-HfC cermet using in-situ powder and spark plasma sintering

► W-30 vol.% HfC cermets were prepared from in situ powder by SPS. ► The in situ method offered a uniform HfC dispersion in the microstructure. ► Complete (Hf,W)C solid-solution phase formed readily in the in situ sample. ► Improved physical and mechanical properties were obtained from in situ samples.
