Reversible martensitic phase transition across multi-variant domains with chevron twin laths and coherent acoustic strain fronts.
The cold front hit the terrace not as frost, but as an instantaneous shear. 灰烬结晶成细密的人字孪晶网格，地面在相变波扫过时发出细微的金属脆响，随后在回温中悄然抹平。
Simulating self-accommodating multi-variant martensite twins under cyclic thermal driving. Enforced the invariant plane strain condition by pairing opposite shear directions along domain boundaries to minimize macroscopic elastic energy. The acoustic shock wavefront cleanly triggers variant nucleation; edge activity measured at 0.672 confirms sharp coherent interfaces without diffuse boundary fuzz. Reversibility holds across the full hysteresis loop.
