Investigation on microstructural properties of transient liquid phase (TLP) bonded IN-738LC superalloy with AMS 4776 filler metal
Bibliographic record
Abstract
In the present study, microstructural evolutions at the joint region of transient liquid phase bonded IN-738LC superalloy were examined. The experiments were carried out at 1100°C with different holding times using Ni–B–Si–Cr–Fe filler alloy, AMS 4776, with B and Si as the melting point depressant elements. It was found that insufficient isothermal solidification of liquated insert caused the formation of continuous centreline eutectic phases. The width of the eutectic decreased with the increase in holding time. Complete isothermal solidification, which precluded the formation of the centreline eutectic, occurred within 45 min of holding time. In addition to the centreline eutectic products, precipitation of boron rich particles was observed at the diffusion affected zone. Homogenisation of isothermally solidified joints at 1120°C for 300 min resulted in the elimination of intermetallic phases formed at the diffusion affected zone and formation of significant γ′ precipitates in the joint region.

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.
