We study specific features of the distributions of alloying elements in secondary carbides for the Ni–13.5Cr–5Co–3.4Al–4.8Ti–7.3W–0.8Mo–0.015B–0.12C multicomponent system. The thermodynamic processes of crystallization are modeled by the CALPHAD method. The results of numerical analyses of the chemical composition of carbides are compared with the experimental data obtained with the help of a РЕМ-106І microscope with a system of energy-dispersive X-ray microanalysis. The influence of alloying elements on the temperature of precipitation of the secondary carbides is analyzed.
