| 1 | 注氘低活化马氏体钢在电子辐照下的缺陷行为显示文摘低活化铁素体/马氏体(RAFM)钢被视为国际热核聚变反应堆以及聚变反应堆的第1壁候选结构材料之一,很多国家均在研究不同的RAFM钢,中国低活化马氏体(CLAM)钢的研究亦正在进行。核聚变会产生氢、氦、氘及氚,这些气体元素与辐照缺陷结合在一起,对材料的辐照性能会产生较大影响。本文对注氘后不同温度下的辐照后微观结构进行研究。试验利用日本北海道大学的JEOL-1300高压电子显微镜研究注氘CLAM钢从室温到873K在1250keV电子辐照下的微观结构变化。研究结果表明,在电子辐照下,注氘产生的缺陷团会出现消失和长大两种现象,意味着间隙型与空位型位错环在注氘过程中同时产生。并研究了注氘产生的空洞。 | 黄依娜 万发荣 乔建生 肖鑫 OHNUKI Somei HASHIMOTO Naoyuki | 2010 | 原子能科学技术2010，44，6： | 3 |

| 18 | Microstructure,hardening and deuterium retention in CVD tungsten irradiated with neutrons at temperatures of defect recovery stagesⅡandⅢ显示文摘Samples of ultra-high-purity tungsten prepared using chemical vapour deposition(CVD)technique were irradiated with neutrons at temperatures T_(irr)=373-483 K(stage Ⅱ of defect recovery)and T_(irr)=573-673 K(stage Ⅲ)up to 0.15 displacements per atom(dpa)in the Belgian reactor(BR2).The study of the microstructure of neutron-damaged samples using transmission electron microscopy(TEM)revealed visible defects with a predominance of dislocation loops.With an increase in the neutron irradiation temperature,the spatial distribution of the loops acquired pronounced inhomogeneity,and their average size moderately increased.Cavities and voids were not observed.Irradiation-induced hardening was found and a linear correlation was obtained between Vickers microhardness and nanohardness for undamaged and neutron-irradiated CVD-W samples.Irradiation of tungsten with neutrons led to a significant increase in the retention of deuterium,which accumulated mainly in vacancy-type traps.Furthermore,the influence of the columnar grain structure in low-dose neutron-irradiated tungsten seemed to be non-trivial upon deuterium retention. | Xiao-Ou Yi Tatsuya Kuwabara Vladimir KhAlimov Yu-Feng Du Wen-Tuo Han Ping-Ping Liu Bin-You Yan Jiu-Peng Song Kenta Yoshida Takeshi Toyama Fa-Rong Wan Somei Ohnuki Yuji Hatano Yasuyoshi Nagai | 2022 | Tungsten2022，4，3： | 0 |
| 19 | Mechanical property and irradiation damage of China Low Activation Martensitic(CLAM) steel显示文摘China Low Activation Martensitic(CLAM) steel is being studied to develop the structural materials for a fusion reactor,which has been designed based on the well-known 9Cr1.5WVTa steel.The effect of tempering temperature on hardness and microstructure of CLAM steel was studied.The strength of CLAM steel increased by adding silicon,and the ductility remained constant.Conversely,while CLAM steel maintained good ductility with the addition of yttrium,its tensile strengths were greatly degraded.Behaviors under electron irradiation of CLAM steel were examined using the high voltage electron microscope.Electron irradiation at 450℃ formed many voids in CLAM steel with basic composition,whereas CLAM with silicon steel did not change the microstructure significantly. | ZHU YanYong WAN FaRong GAO Jin HAN WenTuo HUANG YiNa JIANG ShaoNing QIAO JianSheng ZHAO Fei YANG ShanWu OHNUKI Somei HASHIMOTO Naoyuki | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，11： | 0 |
| 20 | Effect of Deuterium Ion Implantation on Microstructures of Fe-M (M=V, W, Ta) Alloys显示文摘To study the effect of tungsten, vanadium and tantalum on the microstructures in CLAM (China Low Activation Martensitic) steel after irradiation respectively, the microstructures of Fe-M (M= V ,W, Ta) model alloys were investigated after implanted deuterium ions using an ion accelerator at 773 K. After implanted deuterium ion, TEM (Transmission Electron Microscope) observation and EDX (Energy Dispersive X-ray Spectrom) analysis have been carried out. The result showed that tiny voids were observed in all model alloys after implanted the same dose of deuterium ions. The swelling rate in FeTa alloy was the smallest among the three alloys. Unlike FeW and FeV alloys, there was the segregation in FeTa alloy under a fluence of 5×1017 D + /cm2 at 773 K. A theoretical analysis showed that the void growth in FeTa alloy slowed down due to tantalum segregation near voids. It indicates that tantalum plays an important role in the improved irradiation resistance of CLAM steel. | Shaoning JIANG Farong WAN Yi LONG Jianchao HE Pingping LIU Somei OHNUKI Naoyuki HASHIMOTO | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，3： | 0 |
