Formation of eutectic-type microconstituent during transient liquid phase bonding of nickel: Influence of process parameters
Bibliographic record
Abstract
Transient liquid phase bonding of nickel by a filler material containing phosphorus as a melting point depressant was performed to study the effects of process parameters on the joint microstructure. Insufficient holding time for complete isothermal solidification of liquated insert resulted in formation of eutectic-type microconstituent along the joint centreline region. An increase in the eutectic thickness with increase in initial filler gap size was observed in joints prepared at a constant temperature and holding time. The eutectic was observed to serve as a preferred continuous path for crack initiation and/or propagation. Two different observation of influence of bonding temperature on the eutectic formation was made, one in which increase in bonding temperature resulted in formation of thicker centreline eutectic and the second in which preclusion of the eutectic was achieved at a shorter time relative to a lower temperature.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
