Atomic ordering and hardness of nonstoichiometric titanium carbide

Hot filament chemical vapour deposition and wear resistance of diamond films on WC-Co substrates coated using PVD-arc deposition technique

“…This small a 0 value cannot be entirely attributed to non-stoichiometry of TiC phase. In fact, according to Lipatnikov et al [12] and to E. M. Fryt [13], TiC y ( y 1) lattice parameter tends to decrease with y to approximately 4.315 Å for TiC 0.6 . The relatively small value of the lattice parameter of as-deposited TiC must therefore mainly be result from residual compressive stress in the film.…”

TiC–TiB2 composites: A review of phase relationships, processing and properties

“…The trigonal ordered phase was formed below 770 • C, while the cubic ordered phase was observed at higher temperatures. Lipatnikov et al 12 have reported that TiC 0.6 can form a disordered phase. In addition, they reported the presence of Ti 2 C with an ordered trigonal or cubic symmetry and another ordered Ti 3 C 2 phase with orthorhombic symmetry.…”

Characterization of In-Situ TiB/TiC Particle-Reinforced Ti-5Al-5Mo-5V-3Cr Matrix Composites Synthesized by Solid-State Reaction with B4C and Graphite through SPS

“…For the latter, hardness did indeed exhibit a slight correlation with stoichiometry, and declined by roughly 15-20% while decreasing the C/Ti ratio to ~0.5. However, these values are still higher than the TiB values described by Lipatnikov et al and Sundgren et al [46,47]. The decrease in measured hardness of the composite TMC-C could be explained by the generally lower total content of particle reinforcement of only 10 vol.-%.…”
