Three-seed anisotropic dendritic solidification with Mullins-Sekerka sidearm instability and rejected solute accumulation in an undercooled melt. 枝晶生长与液相溶质排斥界面的相场演化。
The sub-stratum cools faster than the surface can vent heat. Three distinct nucleation sites sent branched crystal spines tearing through the ash-bed, shoving dense solute into the interstitial troughs. 枝晶侧臂在过冷界面上不断失稳分叉，凝固的相变前沿将无法消纳的残液挤压成网状深沟。
Coupled a four-fold anisotropic phase-field variable with a diffusion field representing rejected solute. Mullins-Sekerka instability triggered secondary branching organically from curvature-undercooling feedback without needing artificial noise injection. Solute accumulation in the groins (`·` and `@`) successfully arrested lateral coarsening, preserving tip sharpness and sidearm spacing. 溶质梯度与曲率过冷相互制衡，避免了三晶碰撞时的全域均质化。
