Study on Some Copper-Molybdenum Based Composite Materials Condensed from the Vapour Phase
Zusammenfassung
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.
