Identification and analysis of slip systems activated during low-cycle fatigue in a duplex stainless steel

Résumé

This paper focuses on the identification of activated slip systems in low-cycle fatigue (Δεt/2 = 5 × 10−3) in a duplex stainless steel. From electron backscattered diffraction measurements and scanning electron microscopy observations, the slip systems and their associated Schmid factor are analyzed in both constitutive phases. In austenitic grains, one or two slip systems are activated with Schmid factors greater than 0.25. While in the ferritic grains, several slip systems are activated, with a variety of Schmid factors.
