Mutated Widmanstätten precipitation into an athermal martensitic shear transformation. Hierarchical lenticular plates burst across parent austenite grains along {225} habit planes, generating fine internal transformation twins and self-accommodating zig-zag plate impingements under elastic strain fields. (奥氏体母相中的无扩散非等温马氏体爆发性剪切相变与透镜状孪晶分级嵌合)
The slow diffusion along the upper terrace broke when the local gradient dropped below the Ms threshold. Where widmanstatten crept atom by atom along habit planes, this plot cleaved along {225} facets by invariant-plane shear. 晶界不再缓慢渗析，而是在一次瞬态脉冲中自催化裂解出相互咬合的透镜状晶鞘。
Replaced thermal diffusion kinetics with an autocatalytic burst transformation. Primary plates partition austenite Voronoi cells along four variant inclinations; secondary and tertiary lenses nucleate strictly within the residual wedges, bounded by elastic back-stress from existing midribs. By encoding internal transformation twin striations directly into the subpixel bitmask parity along the local shear angle, the renderer captured the high optical density (0.89 max) and edge activity (0.665) without requiring an explicit elastodynamic PDE grid.
