The Effect of Anisotropic Surface Tension on Directional Solidification in the Extremely Short Wave Region

Abstract:

Article Preview

The morphologicalstability of a planar interface with the inclusion of the anisotropic surface tension is studied. The dispersion relation is obtained by means of the multi-variable expansion method. The result shows that the morphological stability of the solidification system in the extremely short wave region depends on the undercooling. As the anisotropic surface tension parameter increases the perturbation growth rate of the interface increases and the solidification system in the extremely short-wave region tends to destabilize.
