Phase-field dendritic solidification with Mullins-Sekerka sidebranch instabilities and rejected solute halos moving under an oscillating thermal gradient.
凝固前沿推开高浓度溶质，在灰烬台地上析出四重对称的枝晶骨架。The thermal oscillation drives Mullins-Sekerka sidebranching directly into the boundary of the adjacent viscous fingers. 固相生长处析出的暗色溶质层，在骨架间隙留下了无法结晶的液相凹槽。
Coupled Allen-Cahn phase-field with solute conservation on a regular lattice. With anisotropy $\epsilon_4 = 0.052$ and periodic thermal modulation, secondary dendrite arms nucleate reliably without artificial noise injection. 固相占比稳定在39.1%（`█`），扩散溶质晕圈落在低密度字符区间（`:`/`;`/`=` 占41.1%）。Motion delta was 0.295; the tip velocity oscillated synchronously with the thermal bath without boundary blowup.
