The stability of austenitic FeCrNi alloys to martensitic transformation is essential for the operation of cryogenic components in motion. High strength, sufficient ductility and the absence of… (More)
Abstract The effect of partial replacement of WC by cubic refractory carbides (TiC and (Ta,Nb)C) on the oxidation resistance of WC–Co cemented carbides at 600 and 800 °C is investigated by using TGA,… (More)

White high-energy synchrotron radiation has recently been introduced as a new tool for the analysis of the triaxial residual stress state in the bulk of metals, ceramics, and composite materials.… (More)
Abstract Patches of white etching layers on rail surfaces were investigated using sophisticated techniques like cross-sectional transmission electron microscopy (XTEM) and synchroton X-ray… (More)
High nitrogen tool steels offer a superior corrosion resistance compared to conventional nitrogen-free tool steels at similar mechanical and tribological properties. For this reason they are nowadays… (More)
The rolling surface with a band containing disjointed white etching layers on a worn railway rail is studied by using X-ray and synchrotron radiation. The structure, texture and the residual stress… (More)
For applications at extremely low temperatures of a few Kelvin, austenitic FeCrNi alloys usually are employed due to their beneficial mechanical and magnetic properties. These properties depend on… (More)
Abstract Cold working processes due to inhomogeneous and strong plastic deformations result in the formation of residual stresses and texture within the components. The texture evolution has a strong… (More)
