Effect of ordering on the structure and heat capacity of cubic vanadium carbonitrides VCxNy

Abstract:
Experimental results are presented on measurements of the crystal structure and heat capacity of nonstoichiometric cubic vanadium carbonitrides VCxNy (x + y = 0.85) in the region of disorder-order phase transitions. It is found that ordered phases V6(C,N)5□ and V8(C,N)7□ with the structures of the V6C5 and V8C7 types form in vanadium carbonitrides at a temperature of ~1100 K through the first-order phase transition mechanism. The channels of disorder-order transitions are determined. It is found that, in the nonmetal sublattice of the detected ordered phases, C and N atoms form one sublattice and structural vacancies □ form another sublattice. C and N atoms are randomly distributed in their sublattice.
