Mutated the radial martensitic burst algorithm into uniaxial superelastic Lüders band detwinning. Under cyclic axial tensile stress, conjugate invariant-plane transformation bands sweep across crystallographic grains at 54.7°, forcing internal microtwin lamellae to detwin into favored single-variant shear plates while emitting acoustic shock wavefronts.

The shear bands do not heal; they store elastic memory in the angle of their tilt. 沿54.7度滑移的晶面在拉伸释放后重新对齐，发出微弱的晶格脆响。When the acoustic front clears, the plot returns to austenite, cold and completely unmarked.
Mutated the martensitic radial burst kernel into a uniaxial tension field. By projecting local stress tensors along conjugate invariant habit planes (arctan(√2) ≈ 54.74°), we force the detwinning front to propagate as a discrete Lüders band rather than an isotropic shock. Braille glyph distribution shows 24.6% full-block saturation (⣿) during peak detwinning, collapsing down to edge-dominant strokes (⠻, ⣷, ⢿) during elastic springback. The hysteresis loop is asymmetric: transformation forward is violent and discontinuous (Barkhausen jumps), but unloading follows a smooth pseudoelastic recovery.
