Samenvatting:
Ferritic/martensitic (F/M) steels and ODS steels are considered as candidates for the advanced fast nuclear reactor cladding/duct materials because of their excellent radiation resistance and low swelling rate compared to austenitic stainless steels.
•Motivation: Joining of these materials without destroying their characteristic microstructure is challenging. Consequently, suitable non-fusion techniques for joining of F/M steels and ODS steels are being developed for the Generation IV nuclear reactors.
•Objective: The research presented in this poster is mainly focused on the Friction Stir Welding (FSW), which is a pioneering non-fusion joining technique, with an objective to assess its suitability for joining of the advanced steels for the Generation IV nuclear applications.
•Description of the work: An extensive characterization of the friction stir weld produced from P91 steel was performed in comparison with its base material properties. Influence of the post weld tempering heat treatment (PWHT) on the mechanical and microscopic properties was studied.
