Effect of Shot Peening on the Fatigue Property of 12Cr Martensitic Refractory Steel
Bibliographic record
Abstract
Shot peening with different parameter was carried into execution on 12Cr martensitic refractory 1Cr12Ni3Mo2VN steel.The residual stress field and the fatigue property on high-temperature(HT) and room-temperature(RT) were investigated.The results show that the residual stress profile is mainly affected by shot peening intensity and surface coverage.The RT fatigue property has a clear and main correlation with the intensity,and the RT fatigue life increases by 6 times after the shot peening with given parameters.Afterward,the surface coverage,which is independent of RT fatigue property,has a significant impact on HT fatigue property of 1Cr12Ni3Mo2VN steel.The HT fatigue life,which would decrease with the increase of surface coverage,increases by two times after the shot peening with 0.12A intensity and 100% coverage.However,the HT fatigue life,compared with the original samples,does not increase when the coverage is of 400%.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
