Abstract
In comparison with plane fatigue, fretting damage may lead to a substantial decrease in the fatigue strength of the material due to the addition of alternating frictional stresses, and the continuous destruction of the surface oxide. Fretting fatigue and plain fatigue tests have been conducted to establish the effect of fretting on the fatigue strength of two nickel-based alloys, Inconel 600 and Incoloy 800 against carbon steel and 410S stainless steel, respectively. The tests were conducted in steam environment at 265°C. The main test variables were the contact pressure 0 < pc < 138 MPa and the mean stress 0 < σm < 138 MPa. The results of the S-N curves for plain and fretting fatigue tests indicated that the reduction factor in the fatigue strength of Inconel I-600 alloy due to fretting is in the range of 2.2 to 3.5, depending on the loading conditions. The results also showed that Incoloy I-800 is more susceptible to fretting fatigue than I-600 by approximately a factor of 1.5.

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.
