N2 - The research activities on modern martensitic 9-12% Cr steels for the application in environmentally friendly power plants at the Institute for Materials Science, Welding and Forming (IWS) are represented by numerous interacting projects. Focusing on mechanical properties of base and weld metal, microstructural characterisation of creep and damage kinetics, weldability, microstructure analysis in the course of creep, modelling of precipitation and coarsening kinetics, simulation of complex heat treatments and the deformation behaviour under creep loading, a comprehensive picture of the material behaviour can be drawn. The individual projects are briefly described and the conceptual approach towards a quantitative description of the creep behaviour of 9-12% Cr steels is outlined.
