Abstract

Six diffusion couples of Ni-Cr-W ternary alloys were prepared, annealed at 1473 K for 72 h and measured by the electron probe microanalysis combined with Whittle-Green method in order to determine the interdiffusion coefficients. The experimental interdiffusion coefficients were critically assessed to obtain the atomic mobilities by means of DICTRA software package. A good agreement has been obtained by comprehensive comparison between the experimental data and the model-predicted diffusion properties, which verifies the reliability of the atomic mobilities of Ni, Cr and W in Ni-Cr-W alloys. The diffusion phenomena, such as diffusion paths and the concentration-distance profiles in the Ni-Cr-W ternary system can be reasonably described by the presently obtained atomic mobilities.
