The effect of technological factors (material, level and shape of surface roughness, on which the condensation is realized; material and thickness of a separating layer; substrate temperature; depths and dynamics of vacuum change; chemical composition and rate of evaporation of initial materials; angle of incidence of vapor flow on condensation surface) on change in mechanical properties of composite materials Cu–Mo with molybdenum concentration from 0 up to 46.5 wt.%., condensed from the vapor phase, was analyzed. Ref. 9, Tabl. 2, Fig. 3.
Key words: electron beam evaporation; pseudo alloys; copper; molybdenum; mechanical properties
