[3D06] Study of irradiation hardening mechanism due to solute atom cluster in a SUS steel

*Ken-ichi Fukumoto1, Takaaki Mabuchi1, Katsuhiko Fujii2 (1. RINE/Univ. of Fukui, 2. INSS)

Keywords:irradaition hardening, stainless steel, solute atom cluster, coherency precipitation hardening mechanism

Using the results of quantitative elementary measurements of solute atom clusters formed in ion-irradiated stainless steel with ATP, the mechanism of irradiation hardening by solute atom clusters will be discussed using a coherent precipitation model by solute atom formation.
