Abstract:

A nickel, silicon and niobium-rich phase observed in heavy ion and neutron-irradiated FV548 steel has been identified as G-phase. It is suggested that the precipitation of nickel and silicon rich phases in austenitic steels during irradiation could reduce the efficiency of silicon as a void swelling inhibitor and may even have a deleterious effect on the long term swelling behaviour of high silicon casts.
