Abstract
The brazeability of AZ31B–H24 magnesium alloy sheet to Zn electroplated, plain carbon steel sheet using an Mg–Al–Zn alloy filler metal and a diode laser heat source has been investigated. While the Zn coating promoted good wetting between the molten filler alloy and the steel sheet, it did not play a direct role in forming the final bond. Bonding between the magnesium alloy and the steel was facilitated by the formation of two transition layers. First, a nanoscale layer of FeAl 3 phase formed on the surface of the steel by diffusion of Al from the Mg–Al–Zn brazing alloy into the steel. Upon further cooling, nucleation and growth of either α-Mg+MgZn eutectic phases or Mg 2 (Al,Zn) 3 phase occurred on the FeAl 3 surface layer.

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
