Abstract
This work investigates the effect of nickel vapourisation on mechanical properties and superelasticity of a NiTi wire by selecting the highest and lowest power within a laser processing window. The dominant phase at room temperature changes from austenite to a mixture of austenite and martensite under low power and high power condition, respectively due to higher nickel loss in the high power sample. Furthermore, the high power sample has more deviation from base material texture (111) B2 that causes deterioration in mechanical properties compared with the low power sample with has 81% of base material strength. Better superelasticity of the low power sample (0.38% residual strain) was explained by the existence of the martensite phase and coarser grain structure in the high power sample.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
