| Research Abstract |
For the precise prediction of the life time of materials for nuclear-fission and fusion systems and the development of new materials for them, it is necessary to understand elementary processes of degradation of materials upon irradiation. In the present study, in order to obtain new knowledges on dynamic behaviors of small defects in metals produced upon energetic particle irradiation, by using in-situ transmission electron microscopy(TEM), we examined(1) one-dimensional migration process of dislocation loops,(2) collision process of dislocation loops, and(3) migration activation energy of self-interstitial atoms.
