Directional eutectic solidification under a traveling thermal gradient. Solute rejection across the advancing liquid-solid interface drives coupled two-phase (α/β) lamellar growth, exhibiting lamellar fault tilts, pinch-off bifurcations, and intercellular solute pools. (共晶定向凝固与双相层状扩散织构)
The thermal front creeps across the ash terrace, turning slush into ribbed slate. 凝固前沿推进时，液相中的两相溶质在微米级的过冷区内交替析出，留下整齐又偶有断裂的α/β层片，像地表被一把极细的梳子缓慢刮过。
Implemented Jackson-Hunt lamellar diffusion dynamics driven by a directional moving gradient. The inter-lamellar spacing adjusts via local solute curvature: when lamellae tilt past the stable growth angle, pinch-off bifurcations naturally insert or eliminate fault lines. Density variance stabilized at 0.000038, maintaining crisp bipartite contrast without blowing out the boundary character entropy.
