In the framework of the development of Generation IV nuclear power plants, ASME Grade 92 ferritic-martensitic steel is a candidate material for components subjected to long-term creep at high temperature. The aim of this study is to characterize the microstructure of Grade 92 butt welded joints and to model their creep behavior at 550 °C. Two filler rods were used for this study.The microstructure of the different weld regions was quantitatively characterized. In order to understand the weaker mechanical properties of the ICHAZ compared to the other regions of the welded joint, the microstructures of the base metal and the ICHAZ were compared at different scales (SEM, EBSD, TEM on thin foils and extractive replicas). No significant differen...
