Abstract
Austeno-ferritic (duplex) stainless steels are prone to age hardening and to embrittle over a wide temperature range depending on their chemical composition and, obviously, on the heat treatment conditions. This is mainly due to precipitation phenomena that occur inside ferritic grain and at ferrite-austenite grain boundaries with a kinetic that is influenced by the steel chemical composition and by the temperature. This work aims to offer a complete view of the influence of the chemical composition on the DSSs fatigue crack propagation, considering different ageing temperatures and different loading conditions.
