Abstract: A comprehensive experimental–theoretical study of the processes of local ordering of multicomponent alloys has been carried out. Atom probe tomography and measurement of electrical resistance during isochronal annealing are used as experimental techniques. Atomistic modeling methods and the multiscale paradigm based on quantum mechanical calculations were used in the theoretical study. The experimental and theoretical approach used made it possible for the first time to detect the initial stage of decomposition of a CoCrFeNi alloy solid solution with the formation of Ni$_4$Cr and Ni$_2$Cr precipitates.

Keywords: high-entropy alloys, ab initio calculations, Monte-Carlo, atom-probe tomography, electroresistivity.
