This paper presents the results of an experiment to investigate the high cycle fatigue properties of the ultra-high strength steel TM210A. A constant amplitude rotating bending fatigue experiment was performed at room temperature at stress ratio R = -1. In order to evaluate the notch effect, the fatigue experiment was carried out upon two sets of specimens, smooth and notched, respectively. In ...

This study proposes a Bayesian inference-based decision framework to quantify the physical uncertainty based on fatigue life tests maraging steel according post-processing treatments and build orientations. Uncertainty quantification of models is performed determine most suitable for metal additive manufacturing process by employing inference. To select one models, we introduce weighted-equival...

The study systematically compares the low-cycle fatigue (LCF) behaviors of novel martensitic steel (22MnSi2CrMoNi) and maraging (00Ni18Co9Mo4Ti). Results show that two types tested have a similar cyclic deformation behavior. softening resistance 22MnSi2CrMoNi is slightly inferior to 00Ni18Co9Mo4Ti at low total strain amplitude. However, gap gradually disappears with increase At same plastic amp...
