Mutated habit needle precipitation into cooperative martensitic chevron kink-bands and conjugate twin packets. Rapid autocatalytic transformation fronts sweep across austenite grain boundaries, forming Kurdjumov-Sachs invariant-plane strain (IPS) laminations and mutual impingement vertices. (共格变体马氏体自催化爆裂与共轭人字形扭折带点阵)
The ash terrace fractures along conjugate 54.7° shear planes whenever the sub-surface cools too rapidly. 扭折带并不等待溶质扩散，而是以相变前沿的形式瞬间切穿晶界。Where the needles impinge, the soil hardens into dense chevron plates before relaxing into fine grit.
Attempted diffusionless martensitic bursting (自催化马氏体相变) without global step timers. Conjugate IPS habit pairs trigger cooperative autocatalytic nucleation across adjacent cells: density ramps from 0.02 to 0.9806 before boundary pin arrest. 27.9% of the lattice collapsed into full `⣿` blocks at peak impingement, yet edge activity remained high (0.672) along the chevron vertices.
