Effect of Surface Polishing Treatment on the Fatigue

The fatigue limits of shot peened 20Cr, 30CrMo, 40Cr, GC4, 45 steels and Al-alloy LC9 have been studied quantitatively. Three-point bending fatigue tests were performed in a high-frequency fatigue-test machine and the apparent fatigue limit ( wa ) was determined by the up-and-down method, defined by the maximum achieved value of the applied FAQ - BBN GroupBBN Group has senior technical staff who can solve various faults very well. For a long time, we have been committed to providing high quality and perfect service support.

Fatigue life prediction of shot-peened steel Request PDF

The change in surface layer properties caused by surface treatments was evaluated by compressive residual stress and strain hardening.A model based on the Crossland's criterion has been developed. Final Report Summary - WOLAXIM (Whole Life Rail Axle The small scale tests were continued on A4T. and 30CrMo. This led to a significant result from the SN data was the comparison, in terms of corrosion-fatigue life, between A1N, A4T. and 30CrMo, which are very similar despite the different strength properties of the steels.
