Concentration dependence of volume changes during sintering of binary systems

Abstract

The dependencies of densification of W-Fe, Ti-Cr and Cu-Cr compacts, during solid state sintering, on the mixture composition, have been investigated. It was shown that ideas on the existence of only S- and V-shaped curves for concentration dependencies of the densification value, as a result of solid phase sintering, were valid. These curve shapes can be explained on the basis of diffusion interaction of components, applying the multiparticle model of a two-component compact.
