Study on Some Copper-Molybdenum Based Composite Materials Condensed from the Vapour Phase
MetadataShow full item record
Design features of equipment are given for realizing high-speed process of electron beam evaporation and condensation. Peculiarities of phase composition and structure of a crystallized pool (melt) on copper base are studied. Assumption was made about interrelation of structure-phase state of the melt and rate of evaporation-condensation. Specifics of surface structure and volume of condensate in different sections (before and after etching) are investigated. Technological defects, their influence on strength and ductility of the condensate at tensile test are considered. Interrelation of temperature dependence of energy of deformation activation, specifics of condensate fracture and technological defects of structure, different by origin, are studied.
