In situ neutron diffraction study of the low cycle fatigue of the alpha-gamma duplex stainless steel

Original language description

The mechanism of the low cycle fatigue in alpha-gamma duplex stainless steel was examined by the neutron diffraction technique performed in situ upon mechanical exposure consisting of the tension-compression cycles with the strain amplitude of 0.8 %. Deformation response of both constituent components, i.e. ferrite and austenite, was studied in situ during the individual applied cycle in detail. Furthermore, the evolution of the residual strains in both phases after tensile and compressive unloading wasmonitored during cycling. Information on the evolution of lattice strains and microstrains has been obtained from the diffraction profiles collected during the fatigue experiment. The results show different deformation behavior and hardening of austenite and ferrite. The evolution of internal stresses and residual stresses detected in both phases during individual cycles is strongly affected by initial stresses present in both phases.
