Periodic layer formation in the growth of dilute binary alloys

Rozas, Roberto E.; Korzhenevskii, Alexander L.; Bausch, … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 394-399

The oscillatory growth of a dilute binary alloy in rapid directional solidification has recently been described by a nonlinear oscillator equation, assuming a uniform diffusion constant of the solute component in both phases. In a more realistic model with a vanishing diffusion coefficient in...
