| Abstract Scope |
Additive manufacturing has become an appealing technique to fabricate three-dimensional metallic materials and components for nuclear reactors. However, response of additively manufactured alloys to high-dose heavy ion irradiations at elevated temperatures is still not well understood. Here, we will present the response of an additively manufactured 316L austenitic stainless steel to ex situ and in situ heavy ion irradiations. Microscopy studies show a reduced defect density in the additively manufactured sample compared with its cold worked counterpart after heavy ion irradiation to 200 dpa. In situ irradiation studies captured microstructure evolutions during radiation and reveal potential mechanisms of enhanced radiation tolerance. The present work advances our understanding on the high-temperature irradiation response of additively manufactured steels for nuclear reactor applications. |
