Abstract
Sintering diagrams, which determine the dominating mechanism of powder sintering at a given temperature, the size of powder grains, and the neck between the grains, may be used to explain the experiments on sintering and solve some practical problems concerning the sintering of metals and ceramics. In this work we have built sintering diagrams for titanium carbide powders of various dispersities. Using such diagrams, we have established that the dominating mechanisms of sintering titanium carbide micro- and nanopowders are the surface and grain-boundary diffusion of substance to the neck between the particles. It is found that the contribution of sintering basic mechanisms in the case of titanium carbide does not depend on the dispersity of powders.
