Investigation of Rolling Fatigue In Locally Predamaged Areas by Microscopic and X-Ray Techniques
Rollers of roller bearings were predamaged by local superheating small surface areas. In these spots, the changes of microstructure and residual stresses were investigated in dependence on the rolling number. The results were compared with observations made in undamaged specimen areas fatigued under the same rolling conditions.
