POSTIRRADIATION DEFORMATION CHARACTERISTICS OF HEAVY-ION IRRADIATED 304L SS

[摘要] Post-irradiation deformation behavior in Ni-ion-irradiated 304L stainless steel (SS) is examined as a function of radiation dose and deformation temperature. For similar strain levels, specimens exhibit a transition from dislocation slip to deformation-induced twinning at 25 degrees C with increasing radiation dose. At 288 degrees C twinning is no longer observed and highly localized slip occurs by the formation of narrow ''channels'' containing a reduced defect density. The observations are discussed in terms of radiation-induced defect character and expected deformation mechanisms.
