- The effects of oversized additive atoms on microstructure evolution in 310S stainless steel under irradiation was investigated. Irradiations of 120 -keV Ar+ were conducted on two types of modified 310S stainless steel at 290 °C and 550 °C. SC-1 was modified with Zr and SC-2 was modified with Nb, Ta and W. Compared with SC-2, low density, smaller cavities formed in SC-1 at 290 °C. When the temperature was increased to 550 °C, different cavity behaviors were observed in the two materials. In SC-1, as the irradiation temperature changed from 290 °C to 550 °C, the average cavity size increased while the cavity density dropped to a lower value; however, in SC-2, the average size and density of cavities shifted to larger values. At 550 °C, low density, larger cavities were observed in SC-1 compared with SC-2. In addition, precipitates enriched with Ni were observed in SC-1, while Nb- and Ta-enriched precipitates were found in SC-2. TEM images, EDS results of precipitates and average size and density of cavities and precipitates are provided.
