Sammanfattning
A detailed understanding of the irradiation-induced damage evolution is valuable when considering materials for extreme environments, such as in fusion applications. In this work, irradiation-induced pointlike defects and their recovery kinetics in vanadium are studied with positron annihilation spectroscopy. The defects were created with 10 MeV proton irradiation at cryogenic temperatures. Several distinct recovery stages are found, at 60 K, 100 K, 150 to 250 K, and 375 to 475 K. These are interpreted as the motion of self-interstitial atoms, monovacancies, clusters of vacancies and multivacancy-hydrogen complexes. These observations allow for estimating migration barriers for the elementary defects.
