Radiation damage in helium ioneirradiated reduced activation ferritic/martensitic steel
The average bubble size increases and the bubble density decreases with an increasing irradiation temperature from 200C to 350C. Both the average size and density of the bubbles increase with an increasing irradiation dose from 2 dpa to 8 dpa. Bubbles with smaller size and lower density were observed in the SMATed samples but not in the un-SMATed samples irradiated in the same conditions, which indicate that GBs play an important role during irradiation, and sink strength increases as grain si
