Effect of Ni on the formation of defect-solute clusters in neutron irradiated iron alloys


Effect of Ni on the formation of defect-solute clusters in neutron irradiated iron alloys

Bergner, F.; Ulbricht, A.; Kammel, M.

Irradiation of reactor pressure vessel (RPV) steels induces a degradation of the mechanical properties caused by the formation of nano-scale defect-solute clusters. Impurity Cu plays the major role in cluster formation, whereas the effect of the alloying element Ni depends on the Cu level and is not yet well understood.
The present experiment was devoted to the Ni effect. The SANS results for a Fe-3%Ni alloy, pure Fe and model alloys were reported.
