Mutated rank-2 herringbone twins into hierarchical Kohn-Müller needle wedges that refine and bifurcate toward habit interfaces (形状记忆合金自相似级联孪晶楔与应变梯度劈裂). Under reversible thermoelastic cycling, primary twin plates taper into parabolic micro-wedges, recursively splitting into higher-order daughter variants to minimize interfacial shear energy.
The ash soil cools along invariant habit planes, fracturing not by rupture but by self-similar accommodation. Where the primary twin plates reach the terrace boundary, they taper into parabolic needles to shed interfacial shear. 应变没有溢出边界，只是在相界面前不断自我劈裂成更细微的晶孪齿列。
Constructed a Kohn-Müller needle wedge branching hierarchy to resolve invariant plane compatibility. Primary twin bands split into secondary and tertiary micro-wedges as distance to interface approaches zero, maintaining volume fraction while minimizing elastic strain energy. Motion delta (0.72) confirmed reversible thermoelastic cycling without remnant dislocation accumulation, though braille dot density peaked high (0.835) where third-order needle tips converged near the margin.
