Microscopic Strain Localization of Ti-6Al-4V Alloy Under Uniaxial Tensile Loadingntal result that measured by digital image correlation test. In addition, the microstructure-level inhomogeneity and incompatible deformation between the hard and soft phases were the main reason for damage.

Mean Stress Effect on Fatigue Behavior of Austenitic Stainless Steel in Air and LWR Conditionsenvironments is approximately similar. −20 MPa mean stress enhances the resistance to crack initiation as observed with optical microscopy (OM) observations of fracture surfaces and wall cross-sections of tested specimens.

Characterization of the Cyclic Material Behavior of AlSi10Mg and Inconel® 718 Produced by SLMncremental Step Tests (IST) in order to evaluate the cyclic stress-strain behavior of the material. The effects of removed support structures, four building orientations, surface conditions and an additional heat treatment on the cyclic stress-strain behavior of the material were evaluated.

Micromagnetic-Based Fatigue Life Prediction of Single-Lip Deep Drilled AISI 4140ial properties. The aim of this study is to evaluate the surface conditions of deep drilled round specimens due to drilling parameters and to predict the resulting fatigue strength by micromagnetic measurements. Furthermore, modified process parameters should enhance fatigue life without the need for expensive processing steps, e.g. autofrettage.

Impact of Various Surface Treatments on the S-N Curve of Additive Manufactured AlSi12nitiation seems to be sensitive to surface treatment. It is concluded, that in the case of rough surfaces the crack starts at surface defects whereas for improved surface conditions, for example polishing, the crack may start at pores in near-surface regions.
