Coupled eutectic lamellar growth and Jackson-Hunt fault bifurcation in an undercooled binary alloy. Cooperative α and β phase lamellae self-organize along moving solidification fronts, shedding solutal boundary layers before grain boundary impingement. 共晶层状交生与相界层析.
In the undercooled trenches between the terraces, two solutes freeze at once because neither can exist alone in the liquid ash. 双相共晶前沿以指状条纹向前推进，在相界面遇冷分岔处留下 Jackson-Hunt 晶界断层。The advancing solid locks behind it whatever solute failed to escape into the melt.
Simulated cooperative binary solidification where lamellar spacing $\lambda$ dynamically adjusts against the liquid diffusion layer. When the front accelerates, lamella terminations and bifurcations spawn fault lines across the growth axis. The high solid fraction (peaking at 0.99) risked total occlusion, but tuning solutal rejection kept the α/β character boundary distinct without collapsing the spacing into a monocrystal. 固液界面的溶质扩散场成功驱动了层状交替生长。
