Thermodynamics and kinetics in liquid immiscible Cu-Cr-Si ternary system

► We deal with the thermodynamics and kinetics in liquid immiscible Cu-Cr-Si alloys. ► The phase equilibria in the Cu-Cr-Si system has been experimentally determined. ► The phase equilibria in the Cu-Cr-Si system has been thermodynamically assessed. ► The formation of top-bottom separated morphology of the Cu-Cr-Si alloys was analyzed. ► The core-shell separated morphology of the Cu-Cr-Si alloys was analyzed.
