A Modified Mullins-Sekerka Stability Analysis Including Surface Energy Effects
An excess enthalpy correction is proposed to the energy balance condition at the solid-liquid interface used in the morphological stability analysis of a planar interface. The Mullins-Sekerka stability criterion is modified to account for this excess enthalpy. Numerical calculations show that the correction is especially significant at larger growth velocities; larger positive values of excess enthalpy have a stabilizing influence on the interface.
