Abstract

One of characteristic feature of stress determination by X-ray diffraction technique is the possibility to analyze stress state in individual phases of a multiphase material. Duplex steel widely used in chemistry and oil refinery equipments is an example of this kind multiphase material consisting of approximately equal quantities of ferrite and austenite. These phases have different mechanical properties that cause a different stress distribution under loading. In the present paper mechanical behavior of a duplex steel and their ferrite and austenite phases have been studied by X-ray diffraction technique. Stress distribution has been analyzed both in elastic and plastic region.
