Abstract :
Radiation effects have been studied in the modified 316L stainless steel and the commercially available stainless steel and tungsten by the heavy ion irradiation simulation and positron annihilation lifetime techniques. The measured positron lifetime data show that the radiation resistant property of stainless steels is much better than that of tungsten, and the modified 316L stainless steel possesses the best radiation resistant property among them. The present experimental results demonstrate that the commercially available stainless steel is better than the commercially available tungsten for a beam window material of an ADS spallation neutron source system, and the modified 316L stainless steel is the best among the three.
