Description

In order to investigate radiation damage mechanism of the China low activation martensitic (CLAM) steel, the proton radiation damage of CLAM steel and the annealing behavior of defect were probed by slow positron beam. It was found that the density of vacancies increased, and the size reached a saturation value, with increasing of irradiation fluence. The whole region of irradiated sample was only slightly damaged. Small vacancies and vacancy clusters were the dominant defects, and were recovered after annealing at 400 degree C. Besides, the effect of minor additive Si on irradiation behavior for CLAM steel was studied. The experimental results showed that additive Si can not prevent proton irradiation defects. (authors)
