Effect of Si concentration on the liquid metal embrittlement susceptibility of advanced high strength steels
Bibliographic record
Abstract
Resistance spot welding (RSW) trials were performed on electrogalvanized steel sheets with 0.6 and 1.5 wt% Si. It was shown that LME cracks were longer in the 1.5Si alloy. Moreover, Atom Probe Tomography (APT) in the vicinity of the crack tips revealed (i) an accumulation of Si at the solid/liquid interface due to the low solubility of Si in the Zn-based liquid and (ii) greater Zn diffusion from the liquid into the bulk steel substrate on either side of the crack for the 0.6Si alloy. Diffusion simulations indicated that a longer time is needed for the solidification of the Zn-based liquid in the 1.5Si alloy compared with the 0.6Si alloy, further suggesting a prolonged period of contact between the aggressive Zn-based liquid and substrate grain boundaries in the case of the 1.5Si alloy.

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.
