在这篇论文， Fe 底 oxide-dispersion-strengthened (ODS ) 的微观结构上的调查合金与高精力的 ²⁰ Ne 离子到在在 0.5T _m (T _m 是合金的融化的点) 被介绍。有传播电子显微镜学的调查发现在谷物边界的虚空的加速的生长，通常是在在惰性气体的培植的条件下面的常规 Fe 底合金的一颗担心，没在 ODS 合金被观察甚至照耀到最高的剂量(12000 at.ppm Ne ) 。原因被归功于到点缺点并且在谷物的在 nano 规模氧化物粒子的接口的 Ne 原子的强壮的套住的提高的再结合。学习证明 ODS 合金由于惰性气体的累积有好抵抗到高温度的内部小粒的 embrittlement，展出处于在在一个熔化反应堆相似的提高的温度的可观的氦生产的严厉状况的申请的突起。

英文摘要：

In this paper, an investigation on the micro-structure of an Fe-base oxide-dispersion-strengthened （ODS） alloy irradiated with high-energy ^20Ne ions to different doses at a temperature around 0.5Tin （Tin is the melting point of the alloy） is presented. Investigation with the transmission electron microscopy found that the accelerated growth of voids at grain-boundaries, which is usually a concern in conven- tional Fe-base alloys under conditions of inert-gas implantation, was not observed in the ODS alloy irradiated even to the highest dose （12000 at.ppm Ne）. The reason is ascribed to the enhanced recombination of point defects and strong trapping of Ne atoms at the interfaces of the nano-scale oxide particles in grains. The study showed that ODS alloys have good resistance to the high-temperature inter-granular embrittlement due to inert-gas accumulation, exhibiting prominence of application in harsh situations of considerable helium production at elevated temperatures like in a fusion reactor.
