Measurement of Crystal Grain Size of Austenitic Stainless Steels under Low-Cycle Fatigue by EBSD Techniques

Abstract:

Electron backscatter diffraction (EBSD) in conjunction with scanning electron microscopy was used to assess the fatigue damage induced in stainless steels. The parameter of the crystal grain size was devised in order to evaluate the fatigue damage in terms of the crystal grain size. It was concluded that the fatigue damage could be evaluated by the EBSD measurements using the relationship between the total strain range, the number of cycles and the crystal grain size.
