Description
| - Výsledky difrakčního experimentu provedeného in situ v průběhu nizkocyklového namáhání přinesly informace o vývoji makroskopického i mikroskopického napětí v obou fázích duplexni oceli a přispěly k popisu únavových mechanismů v tomto materiálu. (cs)
- 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 was monitored 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.
