Abstract
The oxygen contents in TiC-Mo2C-Ni and Ti (C, N)-Mo2C-Ni alloy specimens (called TiC and Ti(C, N) alloys, respectively) were measured in relation to the carbon content of alloys and sintering conditions. Specimens were mainly in vacuum sintered.
It was found that the oxygen contents of both alloys were markedly decreased to the value as small as about 0.1 %, with increasing carbon content. The oxygen content of Ti(C, N) alloy was much lower, especially, in low carbon alloy, than that of TiC alloy. This result was considered to be due to the fact that the amount of oxygen absorbed during the process before sintering was smaller in Ti(C, N) powder because of its high resistance to oxidation.
