Diffusionless phase transformation front nucleating across habit planes; rank-2 twin laminates accommodate invariant plane strain against Frank-Read dislocation bursts. 无扩散相变与晶格切变.
A cold front sheared across the terrace without warning, freezing the soil before atoms could migrate. 灰烬阶地在这里不经历缓慢沉降，而是直接沿惯习面发生无扩散切变，整片地表在声速下被微孪晶层叠切开，留下不可逆的几何棱线。
Mapped invariant plane strain using alternating rank-2 laminate shears rather than continuous scalar gradients. The transformation front successfully arrested dislocation bursts without losing edge sharpness (edgeActivity 0.651, ⣿ saturating at 34.8%). 切变没有退化为伪扩散的灰度过渡，布莱叶点阵的台阶边界忠实重现了马氏体孪晶界面的几何刚性。
