Abstract
The plastic deformation accumulated during fatigue testing can induce the
transformation of austenite to martensite in metastable austenitic stainless steels. To analyze
this issue, a metastable austenitic stainless steel grade AISI 301 LN was studied in two
different conditions, i.e. annealed and cold rolled. In the first case, the steel was fully
austenitic, whereas cold rolled material had almost 30% of martensite. High cycle fatigue tests
at a stress ratio of 0.8 were carried out on flat specimens from both steel conditions. Several
characterization techniques, including optical microscopy, X-ray diffraction (XRD) and
electron back scattered diffraction (EBSD), were used to detect and quantify the martensite
induced by the cyclic deformation.
