用慢正电子湮没谱研究了退火对氢离子辐照Fe和Fe-0.3%Cu合金中VmHn络合物和Cu沉淀行为的影响。S参数的测定结果表明，室温辐照比高温辐照更有利于VmHn配合物的形成。S-W结果证实，即使在0.1dpa的辐照剂量下，Fe-0.3%Cu中也形成了Cu沉淀。退火处理后在损伤区形成了明显的S值峰，表明VmFn复合物被破坏，大量的氢原子逸出。随着退火温度的升高，残余空位缺陷会向表面区域和相反方向迁移。(C)2015爱思唯尔B. V.保留所有权利。
The effect of annealing on VmHn complexes and Cu precipitate behaviours in hydrogen ion irradiated Fe and Fe-0.3%Cu alloys was investigated by positron annihilation spectroscopy using a slow positron beam. The results of S parameters indicated that the room temperature irradiation was benefit for the formation of the VmHn complex compared to the elevated temperature irradiation. The S-W results confirmed the formation of Cu precipitates in Fe-0.3%Cu even at the irradiation dose of 0.1 dpa. The formation of the evident S value peaks in the damage region after annealing treatment suggested that the VmFn complexes were broken and a larger of hydrogen atoms were escaping. The residual vacancy defects would migrate towards both the surface region and the opposite direction with the increasing annealing temperature. (C) 2015 Elsevier B.V. All rights reserved.
