Abstract

Phase stability diagrams of Ti-TiC-TiN-Ti(CN) system were constructed at 1673 K as a function of carbon activity, nitrogen pressure, and characteristics of solution formation. The domains for Ti and Ti(CN) exist in real systems. It was also found that the domain for Ti(CN) is much larger than that of ideal mixing of TiC and TiN. This is because the mixing reaction of TiC and TiN or the nitriding of TiC occurs exothermically. The stable area of nano-sized Ti(CN) was smaller than that of micron-sized Ti(CN) due to the instability of nano-sized Ti(CN).
