摘要：

Microstructural data have been described on Fe-15Cr-xNi-yP alloys in both solution-annealed and cold-worked conditions irradiated in the Fast Flux Test Facility (FFTF) reactor at 638 and 873 K to 5.2 and 8.8 dpa, respectively, where x = 25 to 45 and y = 0.001 to 0.04. The irradiation was carried out on each alloy condition exhibiting two variants in the ratio of Ni-59 isotope. TEM examinations have been conducted to study the role of He/dpa ratio, Ni content, P level, thermal-mechanical condition and irradiation temperature on the development of neutron-induced microstructure. The results obtained show that prior-cold working, higher Ni content and higher P level usually suppress swelling. Higher He generation rate does not always enhance swelling. Phosphide was precipitated only at 873 K.
