ABSTRACT
The equilibrium structure of embedded nanocrystals formed from strongly segregating binary alloys is considered within a simple thermodynamic model. The model identifies two dimensionless interface energies that dictate the structure and allows prediction of the stable structure for any choice of these parameters. The resulting structure map includes three distinct nanocrystal morphologies: core/shell, lobe/lobe, and completely separated spheres.

    The thermomigration (TM) behavior in eutectic SnPb alloy was observed under a constant thermal gradient of 1000 °C/cm. Pb phase was depleting in the hot side, so Pb atom should be the dominant migration species in the current studied conditions. By estimating the depletion atomic volume in...
