The 700 °C power plants currently under development will utilize Ni-base alloys such as alloy 617 for components to be operated at temperatures >650 °C. Due to economic reasons for components or parts of components which are subjected to temperatures <650 °C, 2% Cr or 9-12% Cr steels is used, depending on the required mechanical properties. This makes the dissimilar joining of Ni-base alloys an...
The ferrochrome alloy is produced by electric arc melting of the mineral chromite (FeCr2O4). It is largely used for the production of stainless steels. Increasing the amount of chromium content in the steel allows for increased corrosion and oxidation resistance. Other alloying elements, such as nickel (Ni) or molybdenum (Mo), aid in making the steel more passive and increasing its stainless pr...
There have been numerous efforts to develop creep-resistant materials strengthened by incoherent particles at high temperatures and stresses in response to future energy needs for steam turbines in thermal-power plants. However, the microstructural instability of the incoherent-particle-strengthened ferritic steels limits their application to temperatures below 900 K. Here, we report a novel fe...
The information about the quantitative effects of alloy elements on the hot strength of steels is scarce and contradictory. Its effects can change according to alloy content and specific conditions of the hot forming process, as they can activate different hardening or softening mechanisms. Three empirical approaches were initially adopted in this work to rank and model hot strength in steels i...
