ABSTRACT OF THE DISCLOSURE A composition of material is disclosed which comprises a method of forming a solid solution of hexagonal tungsten monocarbide and molybdenum monocarbide of stoichiometric composition containing between 10 and 100 mole percent molybdenum monocarbide, comprising the steps of: forming an intimate- ly blended mixture of the desired gross composition, heating the mixture to a temperature within the stability domain of cubic (Mo,W)C1-x, lowering the temperature of the mixture to a temperature within the stability domain of hexagonal (Mo,W)C to cause the nucleation of hexagonal (Mo,W)C from cubic (Mo,W)C1-x, and maintaining the temperature of the mixture at the lower temperature for a sufficient amount of time until the formation of the hexagonal (Mo,W)C is complete.
