Isothermal solidification during transient liquid phase bonding of Inconel 738 superalloy
Bibliographic record
Abstract
An investigation was carried out on transient liquid phase brazing of IN-738 superalloy with Ni–Cr–B filler. Conventional models used to model the Transient Liquid Phase (TLP) bonding process assume that boride precipitation does not occur during the joining process. However, a significant deviation from this assumption was observed in all brazed samples as extensive intragranular and intergranular precipitation of chromium and boron rich particles was observed to occur within the base alloy in regions beside the braze/ base metal interface. Application of two diffusion models to the isothermal solidification stage was successful in reasonably predicting the time required to achieve complete isothermal solidification of the liquid insert, which is vital in preventing the formation of deleterious centreline eutectic. Diffusion analysis showed that the boron rich particles formed as a result of substantial solute diffusion into the base metal before equilibration of the liquid–solid phases.

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.
