The effect of structural vacancies on a nature of metal-metal and metal carbon bonds in cubic monocarbides

摘要

Values of specific heat capacity, thermal expansion coefficient, bulk module of elasticity, Gruneisen coefficient, as well as exponents of Buckinham potential and critical characteristics of PV-diagrams determinated by metal-metal and metal-carbon interactions for monocarbides of Ti, Zr, V, Nb in region of homogeneity are calculated. Exponents of the potential indicate that structural vacancies exchange a contribution of chemical bond components in mentioned interactions and generally in compounds.
