Abstract
The strain rates derived from stress relaxation tests are compared to those from creep tests at 760 °C for the superalloy IN738LC for stresses between 500 and 600 MPa. The strain rates agree well from 500 to 575 MPa, but a difference exists at 600 MPa. The results are interpreted in terms of the deformation mechanism controlling the strain rate. It is suggested that dislocation mechanisms control the deformation, but at 600 MPa the mechanisms controlling the creep strain rate differs from that controlling recovery during stress relaxation. The time efficiency associated with stress relaxation testing can be used to advantage within a limited stress range, however, extrapolation of stress-relaxation-derived strain rates may lead to the same erroneous results associated with extrapolation of creep strain rates.

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
