1. First-principles study of the multiple He trapping in defects in vanadium and SiC
Sammanfattning : In fusion environment, large amount of helium (He) atoms are produced by transmutation along with structural damage in the structural materials, causing materials swelling and degrading of physical properties. In this thesis, using first-principles method, I examined the microscopic mechanism of He trapping in vacancies and voids in structural materials (vanadium solid and 6H–SiC composites). LÄS MER
2. First-principles study of defects instructural materials
Sammanfattning : In this thesis, first we focus on the Helium (He) and He bubbles behavior in three kinds of the most promising candidate structural materials for future fusion reactor. These materials are vanadium, silicon carbide (SiC) composites, and reduced activation ferritic-martensitic (RAFM) steels. LÄS MER
