Directional dependence of corrosion fatigue of iron-silicon bicrystals
A directional dependence of the corrosion fatigue behavior of Fe-2.7wt%Si alloy Σ5[100]/(021) bicrystals was observed in a film forming solution. To understand this directional dependence, dislocation nucleation analyses at the opposite crack tips based on the Rice-Thomson concept and continuum elastic-plastic analyses, within single crystal theory, of the near tip fields by finite element method were performed. Explanations of brittle/ductile fatigue crack growth under corrosive conditions and the local crack tip rotation within the interface are offered based on these analyses.
