Description
High energy ion irradiation to simulate neutron damage was applied to study the irradiation effect on stress corrosion cracking (SCC) in stainless steels. Small tensile specimens of commercial purity type 304, high purity type 304L (HP304L) and high purity type 304L containing phosphorus (HP304L+P) were irradiated with 60 MeV He2+ ions by using a cyclotron at 560-580 K, up to a dose of 0.4 dpa. Slow strain rate tests (SSRT) were conducted in high temperature water containing 32 ppm dissolved oxygen (DO). No intergranular SCC was observed on 304 irradiated up to 0.4 dpa. HP304L and HP304L+P irradiated to 0.4 dpa failed by intergranular SCC and exhibited greater increases in yield strength. The results show that simulation irradiation is a potential method for use to study IASCC. Displacement damage by irradiation is essential for the occurrence of IASCC. The different response to the irradiation among the alloys was attributed to their impurity contents and damage characteristics of ion irradiation
