CONTROL OF THE STRUCTURE AND MECHANICAL-PROPERTIES OF THICK VACUUM CONDENSATES USING DISPERSED PARTICLES

This work summarizes the results of investigations of the structural and mechanical properties of two-phase condensates obtained by the simultaneous electron beam evaporation from independent sources of metals (nickel and iron) and of non-metallic materials (oxides, carbides and borides). The mechanical properties are considered in relation to the substrate temperature, the particle diameter, the second phase content, interphase interactions at the particle-matrix material interface and the grain size of the metallic matrix. An extension of the mechanism that controls the strength and ductility of two-phase condensates of the dispersion-strengthened type is presented. © 1979.
