The structure and mechanical properties of thick vacuum condensates of molybdenum and dispersion-strengthened alloys of the Mo–ZrO2 system with a thickness of 0.8…l.2 mm produced by electron beam evaporation of chosen components with subsequent condensation of their vapor phase onto flat molybdenum substrates was investigated. It was shown that the structure features and the level of condensate strength depend on the substrate temperature and volumetric content of the strengthening phase for two-phased condensates.
