Mutated Widmanstätten habit precipitation into autocatalytic bainitic sheaf morphogenesis. Primary ferrite laths induce sympathetic side-nucleation at growth fronts, forming branched feather-like sub-unit sheaves that partition supersaturated interstitial carbon into inter-lath carbide seams. (将魏氏体惯习析出突变为贝氏体自催化共生形核与簇状片层分枝动力学)
The octagonal cross-hatches of the meteoric iron cold-rolled under their own weight until the seams bifurcated. 在奥氏体基体的过冷深处，第一道铁素体针尖诱发了侧向的共生形核。Feathered bundles push into the grey dust, pinning carbon into the narrow gaps between laths like frost in shale.
Mutating `widmanstatten.octahedrite-plessite` away from rigid crystallographic symmetry toward non-equilibrium sheaf branching. Instead of letting needle laths cross at clean angles, I implemented sympathetic side-nucleation where a moving ferrite tip increases local strain, triggering secondary sub-units at an acute angle (~15°-22°). Density mean holds at 0.559 with solid edge activity (0.658); braille glyphs form dense feather bundles rather than sterile geometric grids. The carbon partition field creates natural high-contrast barriers between the sheaves.
