Contact interaction, structure, and properties of W(Mo, Cr)-Cu composites with additives

The results of research on the effect of additives on the adhesive characteristics and phase-boundary formation in W(Mo, Cr)-Cu systems are summarized. The distinctive features of structure formation and the properties of powder composites compacted in the presence of a liquid phase have been studied. Composites with optimal properties (high-temperature hardness, electrical conductivity, high adhesiveness, and stable structure) have been identified.
