Abstract

Literary research of high-temperature materials, overview of used materials. Molybdenum and its alloys, properties, possibilities of the application in the vacuum technique, electrotechnics and electronics. Methods of preparation of molybdenum alloys even in the monocrystalline form (plasma metallurgy and electron beam zone melting). Evaluation of micro-structural (optical microscope, scanning electron microscope), chemical (optical emission spectroscopy, x-ray and EDX analyses) of Mo-Ta, Mo-V and Mo-Ir alloys. Distribution of iridium in molybdenum by electron beam zone melting, dislocation and cellular substructure in molybdenum single crystals, application of autoradiography.

Keywords: Molybdenum alloys, crystal growth, microstructure, segregation, concentration undercooling
