Hot Ductility Study of HAYNES® 282® Superalloy
Bibliographic record
Abstract
The hot ductility of the newly developed Haynes 282 alloys has been investigated in different solution heat treatments conditions using the Gleeble weld thermal simulation method.The ultimate purpose of this study is to assess the feasibility of using this new alloy for the large aircraft engine structures.The strengthening response on cooling down from the solution heat treatment at different temperatures between 1121 and 1135°C with cooling rates of ~0.3°C/s was considerable (~100 HV increase compared with the as-received condition of HV215) and which may jeopardize weldability, not unexpectedly, in γ' hardening alloys.Initial hardness had no or minor influence on hot ductility.Still, the coarse grains achieved by a solution heat treatment heating at 1135°C-2hrs, ASTM 1 compared to initial ASTM 5 did lower the hot ductility.

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.
