Abstract
1. A thermodynamic approach may be adopted for assessing the possibility of a chemical reaction occurring during the welding of unlike materials; in the case of refractory compounds with wide ranges of homogeneity it is necessary to take into account the effect of composition in the homogeneity range on their thermodynamic functions. 2. The extent of the third stage in the diffusion welding of carbides to carbides and carbides to metals is limited by the slowest link of the process, viz., self-diffusion of metal atoms in the crystal lattices of the carbides. 3. In the diffusion welding of refractory metals and carbides optimum welding temperatures monotonically rise with increasing degree of localization of valence electrons in the metallic lattices (metallic sublattices in the case of carbides).
