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...

Joining of dissimilar metals is required for numerous applications in industries such as chemical, energy and automotive. It challenging due to differences melting point, density, thermal expansion the being joined. Common welding techniques involve limiting solidification a narrow area leading high stresses potentially brittle intermetallic phases. Furthermore, geometric complexity these welde...
