Reduced activation ferritic-martensitic (RAFM) steels are a recent class of radiation-resistant steels designed for the structural components of power-producing fusion reactors. In this work an advanced (A)RAFM steel has been developed with superior radiation hardening resistance with respect to the EUROFER-97 upon which it was based.

Coolant-facing alloys in a tokamak will face harsh environments due to the synergistic effect of flowing coolant, mechanical cyclic loadings, and ionising radiation. Reduced activation ferritic/martensitic (RAF/M) EUROFER-97 is one of the top structural alloys selected to be used in fusion, however it was not designed to have excellent corrosi…
