Effects of Helium Implantation and Subsequent Electron Irradiation on Microstructures of Fe-11wt.% Cr Model Alloy
-
Abstract
Helium effects on dislocation and cavity formation of Fe-11 wt.% Cr model alloy are investigated. Single-beam (electron) and dual-beam (He+/e−) irradiations are performed at 350∘C and 400∘C using an ultra-high voltage electron microscope combined with ion accelerators. In-situ observation shows that the growth rate of dislocation loops is reduced in the helium pre-injected specimen. The mean size of cavities decreased in the helium pre-injected specimen. The possible mechanisms are discussed. -
