The effect of Thermal Treatment on Structure and Mechnaical Properties of Composite, Condensing from a Steam Phase, Material of the System Cu-Zr-Y-Mo

The paper presents the results of influence of thermal treatment on structure, hardness, short-term strength, plasticity, and fracture behavior of laminar composite material of the system Cu-Zr-Y-Mo, obtained by the method of electron bombardment evaporation and layer-by-layer condensation from a vapor phase in the temperature range from 290 to 1070 K. It is shown that high-temperature annealing at 1170 K for 3 hours facilitates a 2, 5 … 3 fold increase in the plasticity characteristics of the composite in the temperature range from 290 to 370 K, narrowing of the material hot-brittleness temperature range at about 570 K, and has practically no influence on the material macrostructure, hardness, and strength in the whole temperature range studied.
