Rauchgasseitige Korrosion von Nickelbasislegierungen für zukünftige 700C-Dampfkraftwerke
… rupture strength of 100 MPa at 750°C. Therefore, nickel base alloys are in the focus of material qualification processes. Nickel base alloys are well investigated due to their hot corrosion behaviour. It is known that sodium sulphate may generate hot corrosion on those alloys at temperatures above …

Untersuchungen zum Alkaliverhalten unter Oxycoal-Bedingungen
… from the exhaust products. These processes are based on the combustion of coal with recirculated flue gas that has been enriched in oxygen. To ensure the energy efficiency the oxygen may be provided by a high temperature oxygen membrane. Because of the high partial pressure of CO2 in the flue …

An investigation of corrosion mechanisms of constructional alloys in supercritical water oxidation (SCWO) systems
… pose material performance issues. As potential alloys in construction of SCWO systems, nickel-base alloys are tested. Corrosion in aqueous feed streams of ambient pH values of 2, 1 and 7 is studied both at supercritical (-425⁰C) and subcritical (-300-360⁰C) temperatures with a constant pressure …

Freisetzung anorganischer Spezies bei der thermochemischen Umwandlung biogener Festbrennstoffe
… high temperature corrosion of iron materials and nickel-base alloys. In order to develop technical measures to reduce the amount of alkalis, sulphur and chlorine in the flue gas, an increased understanding of the release behaviour of these pollutants during thermochemical conversion of biomass is …

Surface degradation and creep of Inconel 617 and Haynes 230 at high temperatures
… an environmental degradation of high temperature alloys used for internals and heat exchangers. Depending on the impurity concentration and the temperature, the materials can undergo oxidation, carburization and decarburization, which can be detrimental to the mechanical behavior of the materials. …

Multiscale Modeling of Effects of Solute Segregation and Oxidation on Grain Boundary Strength in Ni and Fe Based Alloys
Nickel and iron-based alloys are important structure and cladding materials for modern nuclear reactors due to their high mechanical properties and high corrosion resistance. To understand the radiative and corrosive environment influence on the mechanical strength, computer simulation works are …
