MECHANICAL PROPERTIES AND TEMPERATURE OF RECRYSTALLIZATION OF SINGLE CRYSTALS OF MOLYBDENUM

摘要

Purity of molybdenum after electron-beam zonal smelting will reach 99-9999-99-99999％, i.e., two or three orders higher than, in industrial molybdenum.n2. On stress-deformation, curves of mono-crystals of purified molybdenum, obtained in tests át room temperature, site of fluidity is not observed, characteristic for industrial polycrystalline molyb¬denum.n3. Mono-crystals of molybdenum after zonal smelting can be rolled into foil to more than 90％ without appearance of visible cracks along its edges at room temperature and possess definite plasticity upon bending at temperature -197°C in liquid nitrogen.
