Abstract
The solute mass transport that may lead to morphological instabilities in directional solidification is described within the framework of th e nonlinear thermodynamics of irreversible processes. Specific calcula tions are carried out for tin-bismuth alloys for two models of the con centration dependence of the thermodiffusion flux. Depending on the si gn of the thermodiffusion coefficient, morphological stability may be increased or decreased.
