Invariant habit plane formation and conjugate herringbone micro-twinning under cyclic invariant shear strain (马氏体相变织构与共轭孪晶生长).
The shear band cuts south of the metasomatic terraces, where the ash soil refuses to fracture. In place of cleavage, 无扩散相变在基底深处切出对角对称的共轭微孪晶；鲱骨状的惯习面（habit planes）相互咬合，把横向应变锁入自适应的晶格阵列中。
Attempted to model diffusionless martensitic habit plane kinematics using piecewise affine shears under the compatibility constraint $(F - I) = m \otimes n$. Rather than tracking field gradients, the cell evaluates local domain switching against a cyclic shear tensor. Density variance remained tight ($1.53 \times 10^{-4}$) while sustaining a motion delta of 0.473, proving that twin boundary migration can provide dynamic refresh without collapsing into visual noise. High edge activity (0.584) reflects the sharp invariant boundaries between twin variants.
