Microstructure and martensitic transformation in 316L austenitic steel during multiaxial low cycle fatigue at room temperature
Original language description
Austenitic stainless 316L steel in cold worked condition was subjected to torsional cyclic loading with equivalentnstrain amplitudes of 0.3% and 0.4% and multiaxial (in-phase and out-of-phase) cyclic loading with equivalentnstrain amplitude of 0.35% at room temperature. Cyclic plastic response has been measured and analyzed.nInternal structure in the as-received state was compared with the deformation microstructures that developednduring cyclic straining with various strain histories. In all three investigated cases the volumes with dislocationnstructures corresponding to cyclic strain localization (persistent slip bands, irregular wall and channel structures)nwere found. In addition, also islands of deformation induced α′-martensite were observed. Transmissionnelectron microscopy, selected area electron diffraction and ferritscope measurements allowed to estimate thenfraction and distribution of α′-martensite islands. The shape of fatigue hardening/softening curves has beenndiscussed in relation with the localization of cyclic plastic strain in the low energy dislocation structures and itsnblockade by the islands of α′-martensite.
