WC-reinforced (Ti,W)(CN)

Microstructure of (W,Ti)C–Co system containing platelet WC

“…In fcc (Ti,W)C-based cermets, the addition of Co or Fe in the binder was found to increase the anisotropy, serving to promote the growth of WC platelets [20]. However, the present study shows that the presence of Co is not a direct cause for the WC platelet formation.…”

“…The morphology of WC from (Ti,W)(CN) also consists of thin platelets with a similar aspect ratio to that of (W,Ti)C. The WC platelet formation is further facilitated in the presence of nitrogen [20]. The most common crystal shape of WC in the WC-Co system is a truncated trigonal prism, and the shape of WC particles is known to be sensitive to the binder content and the composition [21,22].…”

Influence of nickel boride addition on sintering behaviour and mechanical properties of TiC–Ni based cermets

“…Sinterability and thermal shock resistance were improved by addition of secondary carbides such as Mo 2 C, WC, NbC, ZrC in TiC/TiCN composite [13][14][15][16][17].…”

Preparation of a highly toughened (Ti,W)C-20Ni cermet through in situ formation of solid solution and WC whiskers

“…Likewise, it is expected that WC can be used as a toughening agent. WC grains grow anisotropically because the crystal structure of WC is hexagonal [3,12].…”
