vacancy cluster

The experimental results show that the large - size voids are created in tungsten irradiated to 20 dpa , the 10 - vacancy voids are observed in the commercial stainless steel irradiated to 22 . 8 dpa , and the 5 - vacancy voids are detected in the home - made modified 316l stainless steel irradiated to 30 dpa
测量结果表明，钨经过20dpa的辐照后，产生较大尺度的空洞；普通不锈钢经22 . 8dpa的辐照后，出现包含10空位的空位团；国产改进型316l不锈钢经30dpa辐照剂量后，仅产生五空位构成的空位团。
