The effect of anisotropic surface tension on the morphological stability of planar interface during directional solidification 下载免费PDF全文
This paper considers the effect of the anisotropic surface tension
on the morphological stability of the planar interface during
directional solidification. When the expression exhibiting the
four-fold symmetry is included, the modified absolute stability
criterion is obtained by employing the multi-variable expansion
method. The linear stability analysis reveals that for the given
temperature gradient, as the anisotropic surface tension parameter
increases, the stability zone tends to decrease. 相似文献
