Equilibrium diagrams of the carbide systems were examined and constructed of binary and ternary systems which made it possible to propose several generalizations predicting the phase transitions in unexamined, including multicomponent, systems. It was found in most cases that the phase equilibria in the ternary systems of the metal groups IV-VII was determined by the structure of the NaCl type. The limiting content of solid solution carbon of the transition metal cubic carbides can be evaluated using the limiting density of the valency electrons in the carbide phases of the NaCl type.
