Popis:	Methods of scanning electron microscopy, energy dispersive X-ray spectroscopy (EDS) analysis, and electron backscatter diffraction (EBSD) were used to study the microstructure and phase transformations in heatproof copper-nickel alloy1. C-shaped diagrams of kinetics of discharge of the metastable γ' phase and stable η phase were constructed, the temperatures of solvus (stability) phases, and the influence of phase composition on technological embrittlement of the alloy were determined. A regime of thermal treatment of the alloy making it possible to obtain semifinished products with a specified microstructure providing maximum strength and plasticity was proposed.
