Title

Influence of Cold-Work and Phosphorus Content on Neutron-Induced Swelling of Ternary Fe-Cr-Ni alloys

Abstract

Phosphorus additions can either increase or decrease void swelling of simple ternary Fe-Cr-Ni alloys during neutron irradiation, depending on the irradiation temperature, phosphorus level and cold-work level. Phosphorus is shown in these simple alloys to exert its primary influence while in solution. Phosphide precipitation appears to play only a secondary role in void swelling. The role of cold-work is not always to suppress swelling in Fe-Cr-Ni and Fe-Cr-Ni-P alloys, however, particularly at relatively higher irradiation temperatures, where cold-working often increases swelling substantially. Coldworking also appears to alter somewhat and suppress formation of phosphide precipitates.
