Abstract

fetched live from OpenAlex

The influence of gap size and brazing parameters (temperature and time), on the microstructure and properties of diffusion-brazed Inconel 738 (IN-738) superalloy, was investigated using two commercial brazing alloys, Amdry ‘DF3’ and Nicrobraz 150. The residual liquid present at brazing temperature was observed to transform on cooling into centreline eutectic constituents in ‘NB 150’ brazement while three different dispersed intermetallic phases were observed in the ‘DF3’ joint. The volume fraction of the second phases increased with gap size in both ‘NB 150’ and ‘DF3’ brazements. In addition to the centreline eutectic constituents, nickel and chromium rich borides were observed at the melt back zone in samples brazed below the Ni 3 B eutectic temperature of 1093°C, and above this temperature only chromium rich borides were observed. Joints containing the second phase intermetallics in ‘NB 150’ and ‘DF3’ brazed materials were found to exhibit tensile properties inferior to that of the base alloy.

Teacher imitation

Not 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.
