Abstract
Vacuum brazing of Nb and stainless steel using Cu-Ti and Cu-Co-Ti filler metals was studied.Under the brazing condition of 960 ℃/20 min two Fe-and-Nb-rich reaction layers were formed respectively at the interfaces between Nb and the brazing seam,and between the brazing seam and the stainless steel.Compared with the joint brazed with Cu-Ti filler metal,the content of Cu in the reaction layer adjacent to the stainless steel is higher than the joint brazed with Cu-Co-Ti filler metal,so is the content of Nb in the brazing seam.The ambient-temperature tensile strength of the joint brazed with Cu-Co-Ti filler metal is slightly higher than that brazed with Cu-Ti filler.

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
