AFM study of the surface deformation of austenitic stainless steel irradiated by He+ ions
Source abstract
Abstract
Abstract Atomic force microscopy (AFM) was employed to confirm the validity for studying the surface deformation by radiation damage. Distinct swelling was noted by AFM observation in austenitic stainless steel SUS316 specimens which were irradiated by 200 keV He + ions in the range of dose from 2.4×10 16 He / cm 2 (0.6 dpa) to 7×10 17 He / cm 2 (17.5 dpa) at 673, 773, 823 and 873 K. The step height due to He ion-induced swelling showed an obvious dependence on irradiation dose and temperature. It was found for the first time that sharp ridging along the grain boundaries occurred, suggesting He atom agglomeration at high doses and temperatures.
