Towards the development of mechanistically-based design rules for corrosion fatigue in ductile steels

This paper shows how the crack growth characteristics of materials (e.g. A 533-B and Ducol W 30) used in nuclear pressure vessels can be used to check the design lines. It also points out not only where changes in the crack growth mechanism in different environments can result in differing lifetime predictions, but also where more work is required to substantiate fully or extend the changes in design curves that are already indicated as necessary.
