AbstractA recent method for analysing the cohesion of transition metal carbides is applied to the carbides of tungsten. In the most interesting of these, WC, the W atoms are not close packed but are arranged in a simple hexagonal sub lattice of lower coordination number.

High-Strength Tungsten Carbides
1971It is well known1,2 that the mechanical properties of sintered tungsten carbide-cobalt alloys are critically dependent upon carbon content. Only when the carbon content corresponds closely to the theoretical value for WC, i.e. 6.13 weight %, are two-phase structures (WC and a Co-rich solid solution) observed.

Atomic ordering of strongly nonstoichiometric compounds like carbides of transition metals is a very widespread phenomenon. The lower tungsten carbide \(\mathrm{W}_{2}\mathrm{C}_{y}\) is a strongly nonstoichiometric interstitial compound and has a wide homogeneity interval \(\mathrm{WC}_{0.34}-\mathrm{WC}_{0.52}\) at a temperature \(\sim \)3000 K.

Ballistic impact experiments of tungsten carbide projectiles onto tungsten carbide targets
2008The dynamic behaviour of similar grades of 6.5-10.3% Co WC hardmetals has been investigated using high speed photography in the velocity regime 130-500m/s using two different techniques: AP core-core impact and sphere-disc impact tests. Failure has been shown to occur along the Co matrix, with slight evidence of trans-granular fracture at higher impact
