Abstract
- In order to understand the evolution of materials under irradiation conditions similar to those in future fusion reactors, we have irradiated high purity iron in situ in a transmission electron microscope with 1 MeV Fe+ ions while simultaneously implanting 15 keV He+ ions, at 500 °C. Once not, vert, similar1 dpa/500 appm He were reached, helium bubbles and large dislocation loops were observed. The study reveals that helium bubbles nucleated heterogeneously: a majority of them were observed inside the large dislocation loops. 2011 Elsevier B.V. All rights reserved.
