Effects of addition-carbides such as Cr3C2, ZrC, NbC, Mo2C, TaC and WC on some properties of high carbon TiC-15% Ni and TiC-10% Mo-15%Ni alloys were investigated. Specimens were vacuumsintered at 1380 to 1480°C for 1.5 hr.
The results obtained were as follows; The addition of WC was found to be effective in increasing the strength of TiC-Ni alloy, though the effect was inferior to that of well known Mo2C. In the case of TiC-Mo-Ni alloy, the addition of each carbide except for Mo2C was confirmed to decrease sharply the strength.
