Abstract
Abstract— Effect of transformed martensite during low temperature fatigue in metastable 304 stainless steel on low temperature toughness were investigated. Low temperature fatigue was mainly conducted at R= 0.1 with maximum stress of 1030 MPa at −196°C. The amount of martensite during fatigue cyclic deformation was related to the reduction of impact toughness and to the apparent fracture toughness. Beyond 30% of martensite formation, a strong decrease of low temperature impact toughness was found. This phenomenon is related to the phase stability of the metastable austenitic phase.
