Abstract
This study presents the successful development of a new high γ′ nickel-based superalloy, LW 4280, using laser powder bed fusion. Microstructural analysis revealed the absence of γ′ precipitates in the as-built condition. A designed sub-solvus heat treatment resulted in a bimodal distribution of γ′ precipitates. The heat-treated specimens displayed yield strength of 1038, 904, 690, 500, 333, 264, and 169 MPa, the ultimate tensile strength of 1455, 1055, 807, 621, 424, 329 and 205 MPa, and elongation of 26%, 26%, 17%, 13%, 24%, 19% and 30% at 21, 760, 871, 927, 982, 1038, and 1065 ⁰C, respectively. Stress rupture tests on heat-treated specimens displayed good rupture characteristics, with rupture times of 190, 205, and 42 h at 871, 927, and 981 °C for stresses of 276, 152, and 138 MPa, respectively. A fractographic analysis was conducted on both the tensile and stress-ruptured specimens to comprehend the failure mechanism.

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
