| Outline of Final Research Achievements |
This is an experimental study which aims to evaluate irradiation hardening not by hardness but directly by nanoindentation. As a main achievement, micro-pillar compression test method was examined to evaluate mechanical properties of the ion-irradiated material. Also, the pop-in phenomenon of a single crystal material by nanoindetation was investigated to reveal ion-irradiation effect on the critical shear stress. In addition, a new analysis method for nanoindentation hardness test on ion-irradiated materials were propesed.
