Abstract Austenitic–ferritic duplex steels are used for structural applications when high strength in combination with excellent corrosion resistance is required. Many of these applications imply cyclic loading and hence, fatigue damage needs to be considered for dimensioning.

Abstract The S–N curves at very high cycle fatigue (VHCF) regime for the base material and the friction stir welding (FSW) joint of 7050 aluminum alloy present multi-stage shapes with an inflection point at about 108 cycles in the study. In the regime between 1 × 106 and 5 × 107, the fatigue crack initiates at the thermo-mechanically affected zone ...

The behavior of short fatigue cracks during Very High Cycle (VHCF) Fatigue of duplex stainless steel
Engineering Fracture Mechanics, 2015Abstract During VHCF loading of duplex steels fatigue damage starts within the softer austenite phase. Depending on the spatial mismatch between the slip systems of neighboring grains, intergranular or transgranular fatigue cracks are initiated. If these cracks can propagate or are blocked depends on the interactions with the local microstructure ...

How to Deal with Very High Cycle Fatigue (VHCF) Effects in Practical Applications?*
Materials Testing, 2012Abstract Fatigue designing of high-stressed engine components is a key factor for reliable power train systems in automotive industry. In this context load assumptions are very important since this is attended with a pre-designing of important machine elements.

Abstract Selective laser melting (SLM) is a novel technique in laser additive manufacturing which uses laser energy to melt powder material according to the geometry of the computer aided design (CAD) model provided to the SLM system. The process uses a layer-wise manufacturing process which ensures that the manufactured parts possess good mechanical

Abstract In the present investigation high-frequency fatigue tests on welded specimens with trimmed surfaces were carried out by means of an ultrasonic fatigue testing system (UFTS). The wave-like distribution of the load amplitude along the longitudinal axis of the UFTS specimens with a maximum in the minimum cross-section (at about the half length)

AbstractA microstructural simulation model is proposed which accounts for damage accumulation in shear bands and deformation‐induced martensite formation in a metastable austenitic stainless steel (AISI304). The model is numerically solved using the two‐dimensional (2‐D) boundary element method.

Abstract Many components have to withstand a very high number of loading cycles due to high frequency or long product life. In this regime, the period of fatigue crack initiation and thus the localization of plastic deformation play an important role.
