Show more >low-alloyed TrIP steels are well known since the beginning of the 21st century and used for automotive applications to ensure the passive safety. however, although their behaviour is fully investigated at a monotonous behaviour, the case of cyclic loading is not well studied. The present work describes in detail the heterogeneous-microstructure evolution of a high-strength steel (TrIP 800 steel) at the low-cycle fatigue conditions. based on the extended investigations (via the optical and elec-tron microscopy, the electron backscattering diffraction), we propose suggestions on the influence of phase composition on the mechanical properties and the crack-ini-tiation processes. The preferential places of the crack nucleation caused by fatigue are detected, and the completeness of phase transformation via the induced plastic-ity is evaluated.Show less >
