Feasibility of Using Oxide Thickness Measurements for Predicting Crack Growth Rates in P91 Steel Components
… temperature components fabricated from ferritic steels commonly used in power</p> <p>plants that run on fossil fuels. To implement this technique, it is necessary to fully understand the</p> <p>kinetics of high temperature oxidation in these steels. In this study, the oxidation …

Stress and creep damage evolution in materials for ultra-supercritical power plants
… creep strength enhanced ferritic (CSEF) 9-12% Cr steels have been identified as the most promising class of materials for some of the key components in ultra-supercritical fossil-fired power plants, including the main steam pipes, headers and superheater tubings. These steels are less costly, and …

TRANSITION METAL COATINGS FOR ENERGY CONVERSION AND STORAGE; ELECTROCHEMICAL AND HIGH TEMPERATURE APPLICATIONS
… metal diffusion coatings of Ti and Zr atop P91 steel were created and tested for their ability to prevent corrosion in an oxidizing atmosphere at elevated temperature. Using pack cementation, diffusion coatings of thickness approximately 12 and 20 µm are obtained for Ti and Zr, respectively. …

Influence of post-weld heat treatment (PWHT) on the tensile behaviour of P91 weldments
… factor for successful installation of Grade 91 steel for high pressure-high temperature applications in power plant is optimised welding and post weld heat treatment (PWHT) which restores homogeneous mechanical properties after welding. Although optimum PWHT is prescribed in standards, …

Testování lomové houževnatosti za vysokých teplot s využitím miniaturních CT těles
… Pro účely experimentální práce byla z oceli P91 vyrobena zkušební tělesa standardní a čtvrtinové velikosti. J-R křivky byly měřeny v rozsahu teplot 23°C až 600°C. Na výsledcích nebyl prokázán vliv velikosti při pokojové teplotě. Provedené experimenty spolu s fraktografickou analýzou prokázaly …
