Abstract :
Examinations of specimen size effects on tensile properties were performed with and without neutron irradiation. Specimen thickness was varied to investigate the effect of aspect ratio as well as the thickness itself. Thickness dependence of yield stress, aspect ratio dependence of ultimate stress and aspect ratio dependence of ultimate strain showed good consistency and reproducibility even in heavy neutron irradiation condition. The effect of specimen size on yield stress and ultimate stress was small, but the ductility showed significant dependence on specimen aspect ratio.
