Relationship between some properties of carbides and nitrides of the transition metals and their electronic structure

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

  1. 1.

    The variation of the physical and thermodynamic properties of carbides and nitrides of the transition metals is analyzed. On this basis, it is shown that, in addition to collectivized electrons, the interatomic bond in these compounds is substantially strengthened by the overlap of the electron shells of ions. The maximum concentration of collectivized electrons is found in carbides and nitrides of the transition metals of group IV.

  2. 2.

    It is necessary to distinguish between two groups of properties characterizing the strength of the interatomic bond. Moduli of elasticity to a large extent characterize bond deformability, while melting points characterize bond rupturing energy. Carbides and nitrides of the metals of group IV have the greatest interatomic bond energy, while carbides and nitrides of the group VI metals have the least bond deformability.

  3. 3.

    On the basis of considerations concerning bond polarization, an attempt is made to explain the phenomenon of reduced plasticity of metals in the presence of other elements and the nature of the brittleness of carbides and nitrides of the transition metals.
