Abstract
AISI 316L austenitic stainless steel is widely used in nuclear and chemical industries for structural components that are submitted to cyclic deformation and stresses. The influence of low temperature (~ 400 °C) plasma nitriding on the crystallographic texture and fatigue durability of 316L has been investigated. Electron back-scattering diffraction measurements show that nitriding enhances the <001> and <111> texture components while the <110> one vanishes. Series of fatigue tests carried out in air at room temperature in the low cycle fatigue range show a significant improvement of the fatigue life. Results are discussed taking into account the residual compressive stresses in the nitrided layer.
