Abstract

Effects of damage rate on defect structural development in Ni and Ni-Sn were studied by the comparison of neutron irradiation with Ni ion irradiation. Special attention was paid to the damage structural evolution near grain boundaries which was affected by the one-dimensional (1-D) motion of self-interstitial atom (SIA) clusters. The 1-D motion of SIA clusters was observed in Ni irradiated with low fluence in both cases of neutron irradiation and ion irradiation. The alloying element Sn prevented the 1-D motion. The irradiation temperatures to cause the same damage structural evolution in Ni and Ni-Sn was shifted to high temperatures (200 K and 100 K, respectively) with increasing damage rate.
