Such properties as microstructure, transverse-rupture strength, thermal conductivity, thermal expansion coefficient etc. of sintered TiC0.7-N0.3- and TiC0.5N0.5-WC-16.4 vol%Ni alloys (called 7/3 and 5/5 alloys, respectively) were studied as a function of WC content. It was confirmed that WC phase can be retained in the structures as a nonequilibrium state when the WC content increases more than about 22 and 10 vol% in the 7/3 and 5/5 alloys, respectively. It was noted that the alloy, in particular, the 5/5 alloy having WC phase in nonequilibrium state shows a high thermal conductivity accompanied by a low thermal expansion coefficient, as well as the excellent mechanical properties.
