Fu, J. (author), Davis, T. P. (author), Kumar, A. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Oxide dispersion strengthened (ODS) steels are leading candidates for structural materials in nuclear fission and fusion power plants. Understanding the nature of nano-oxide particles in ODS steels is vital for a better control of the microstructure and mechanical properties to further their applications. In this study, electron microscopy...journal article 2021

Fu, J. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Oxide dispersion-strengthened (ODS) Eurofer steel was laser welded using a short pulse duration and a designed pattern to minimise local heat accumulation. With a laser power of 2500 W and a duration of more than 3 ms, a full penetration can be obtained in a 1 mm thick plate. Material loss was observed in the fusion zone due to metal...journal article 2021
