Interface Movement

The phase field simulation of interface movement and interdiffusion microstructure in a binary diffusion couples was developed. The diffusion couples with nonequilibrium concentration for single phase or single phase and two-phase including the temperature and mobility effects were studied. It’s shown that the interface movement and the atoms diffusion direction were determined by the magnitude of relative concentration difference between the initial concentration and the equilibrium concentration, the distance of interface movement and interdiffusion flux increases as the temperature or the mobility increasing, and the large mobility makes the particles coarsening faster.

nterdiffusion in the Cu|Cu30Zn diffusion couples under a strong gravitational field was investigated at 400. The Cu-Brass diffusion couples were prepared by electrolytic plating method. Two samples were centrifuged at 0.4×106G for 60 hours. The initial contact interface was perpendicular to the gravitational force direction. The two different orientations of the samples were studied: with Cu 1) downside and 2) upside of the gravitational force direction. It was found that interdiffusion was markedly affected by the gravity field. This was caused by the sedimentation of atoms where heavy Cu atoms move in the direction of the strong gravitational field. A numerical simulation of the sedimentation process is self-consistent with experimental results.
