Conclusions
Judged by the character of their elastic strain, zirconium and titanium carbides may be regarded as elastically isotropic materials. Under conditions of vibratory milling the main cleavage planes in these carbides are the planes {110}. Carbides of nonstoichiometric compositions are more brittle. The changes in strain behavior exhibited by the carbides in their homogeneity ranges are determined by the combined operation of the structural and electronic factors. In the Group IV carbides these two factors have opposed effects, but in Group V carbides they operate in the same direction. Arranged in order of increasing brittleness, on the basis of microplasticity as measured by rms strain, stoichiometric carbides form the series NbC < ZrC < TiC.
