Abstract
The weld heat affected zone (HAZ) of tungsten inert gas (TIG) welded cast IN 738 superalloy has been examined. HAZ microfissuring was observed in alloy welded in solution treated and overaged conditions. Closer and careful microstructural examination by analytical scanning electron microscopy revealed the liquation of boride, sulphocarbide, MC type carbides, γ′ precipitate particles and γ-γ′ eutectic, which were present in the preweld alloy, and the formation of resolidified constituents along the microfissured HAZ grain boundaries, thereby indicating that HAZ cracking in this alloy involves liquation cracking. Liquation of these phases, as well as characteristics of the intergranular liquid film contributing to the low resistance to HAZ cracking of the alloy have been examined and are discussed.

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
