The project will assist in the development and long term life prediction of newly-developed 9Cr ferritic/martensitic steels (E911) by providing an understanding of the evolution of their microstructure. Microstructural modelling will be employed to predict the effects of long term exposure at service temperatures on intea-and inter-granular precipitate size distribution, so that estimates of any changes in mechanical properties over these long periods can be made. Equally importantly, modelling will be applied to forecast the changes in grain boundary chemistry expected during welding of the alloys, because the steels exhibit intergranular cracking in the weld regions. The models will be validated using a variety of advanced analytical techniques, primarily field emission gun transmission electron microscopy with EDA and PEELS plus surface analytical methods, which are all available at Loughborough. The predictions made should be generically applicable to all ferritic engineering steels.The project is intended to complement the DTI PIPPE Coal R&D programme, which is co-ordinated by Mitsui Babcock, one of the collaborators in this proposal. EPSRC mission objectives are strongly supported by the project because it incorporates well with the Foresight Clean Coal Technology initiative and because it brings together industry and academia in a study involving microstructural modelling.
