Structure of deformed polycrystalline zirconium carbide

Numerous studies have been conducted on the transition metal carbides for establishing the regularities of their plastic deformation [1, 2]. However, the relationship between the evolution of the deformation microstructure, the structural changes occurring at the micro-and the macrolevels, and the mechanical properties of the polycrystalline materials has not been investigated in sufficient detail. In view of this, we studied the dislocation structure of ZrCx at different stages of deformation and over a wide range of temperatures and related the structural characteristics with the changes occurring in certain mechanical properties.
