Structure, physico-chemical, mechanical, and operational characteristics of condensed composite materials of the Cu-W system for electric contacts

The authors studied the structure, electro-physical, chemical, and mechanical characteristics of composite materials of the Cu-W system with the content of the components from 0 to 100 mass%. The composites were obtained by the method of electron-beam evaporation of the initial materials with a subsequent joint condensation on a steel substrate and vacuum annealing at 900°C during 1 hr. Mechanical characteristics of the materials were determined in the temperature range from 20 to 800°C in vacuum not lower than 0.1 Pà .
