Measurement of diffusion coefficients of Au in liquid Ag with the shear cell technique

Abstract Diffusion coefficients of Au in liquid Ag were measured at the temperatures 1300 K and 1500 K by using the shear cell technique. The adopted technique was a modified long capillary method which had a diffusion couple configuration. Obtained diffusion coefficients of Au in liquid Ag were respectively 2.30 × 10−9 m2 s−1 at 1300 K and 3.16 × 10−9 m2 s−1 at 1500 K, which were in good agreement with calculations based on the hard sphere mixture model.
