Abstract

The paper describes the structural features and properties of condensed composites based on copper and refractory metals (W, Mo, Cr). It is established that these condensed materials have a lamellar structure with a hierarchy of macro- micro- and submicron levels. In the condensed materials based on copper and chromium, oversaturated chromium solid solutions form and decompose. Examples of applying the Си-Mo, Cu-W, Cu-Cr, and Сr-Аl2O3 composites condensed from the vapor phase to produce electric contacts and electrodes are shown.
