Development and Improvement of 9-12%Cr Steels by a Holistic R&D Concept

Abstract:

The research activities on ferritic / martensitic 9-12% Cr steels at the Institute of Materials Science, Welding and Forming (IWS) are represented by a network of 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. 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.
