Interdiffusion in the face-centered cubic (fcc) Co-W binary alloys was investigated by the diffusion-couple technique between 1273 K and 1573 K (1000 °C and 1300 °C), on which interdiffusion coefficients of the binary alloys up to 12 at. pct W were evaluated by using the Sauer-Freise method. The interdiffusion data were assessed to develop the atomic mobility for the fcc Co-W alloys and its validity was tested by simulating the diffusion-couple experiments.
