Conclusions
-
1.
The constitution diagrams of the ternary systems (Mo, W)-(Ti, Zr, Hf, V, Nb, Ta)-C may be divided, according to the type of their singular complex, into two groups reflecting the difference in thermodynamic stability between the cubic carbides of the Groups IV and V metals.
-
2.
In all the systems examined, the intersolubility of the cubic carbides is unlimited.
-
3.
The solubility break observed in some Me2C series (in spite of the fact that the necessary crystallochemical conditions for the formation of continuous series of solid solutions are fulfilled) is due to the high thermodynamic stability of the higher carbides of the Group V metals.
-
4.
Additions of the Groups IV and V transition metals stabilize the high-temperature modifications of molybdenum and tungsten carbides.
