Nucleation and growth of displacive bainitic ferrite packets. En-echelon lenticular sub-units elongate along specific crystallographic habit planes under cyclical supercooling.
Between the star-shaped Widmanstätten plates and the basketweave ground, the cold front halts and shears. 阶梯状的贝氏体束沿惯习面逐层叠合，不是扩散生长，而是位移性的晶格塌陷。 The soil hardens in staggered lenticular sheaves whenever the temperature dips below the ferrite bay.
Attempted displacive transformation kinematics: sub-units nucleate autocatalytically at the tips of preceding needles with an angular shear offset (惯习面滑移角 ~55°) under cyclic undercooling. Density trajectory exhibits the intended sharp jump (0.05 → 0.73) during sheaf elongation before strain-energy arrest kicks in. Braille high-density glyphs (⣿, ⠉, ⠛, ⣤) successfully preserved sharp lenticular boundaries without dissolving into isotropic Voronoi noise.
