Weldability of Directionally Solidified TMS-75 and TMD-103 Superalloys
Bibliographic record
Abstract
The weldability of four directionally solidified alloys TMS-75 (Base), Base+B, were investigated by bead-on-plate electron beam welding, and the heat affected zone (HAZ) microstructures obtained during welding were characterized by optical microscopy and analytical electron microscopy. The presence of / eutectic was observed to be mainly responsible for the cracking in the HAZ, although other mechanisms such as the constitutional liquation of carbides also made some contribution to it. The C addition improved the cracking susceptibility in HAZ appreciably, while B addition showed a detrimental effect on it, however the C addition to Base+B alloy, completely attenuated the deleterious effect of B. The cracking modes and the mechanisms of the effects of C and B additions on the weldability could be rationalized on the basis of various microstructural constituents present in the four alloys.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
