| Popis: | 1. A study was made of the vacuum sintering of pure TiC and TiC with an activating addition (1% Ni). 2. The addition of 1% of nickel to TiC activates the sintering process. The relative density and linear shrinkage of nickel-containing titanium carbide sintered at 1300°C are the same as those of pure titanium carbide sintered at 2200°C. 3. During the vacuum sintering of TiC with a nickel addition, the nickel evaporates over the temperature range 1500–1800°C. Specimens sintered in a vacuum at 2000°C contain virtually no nickel. 4. High-temperature heat treatment has no significant effect upon the lattice parameters of TiC and TiC + 1% Ni, which shows that no decarbidization of TiC occurs in the course of vacuum sintering at high temperatures. |
