| 1 | 中子辐照诱导压力容器钢中磷的偏析显示文摘中子辐照引起的核反应堆压力容器钢中磷的晶间偏析是导致核反应堆压力容器脆性断裂的主要因素之一.本文提出了预 测核反应堆压力容器钢中杂质元素(主要是磷)晶间非平衡偏析的溶质拖拽模型,并且与速率理论模型进行了对比.该模型的预测 结果与最近发表的压力容器钢(包括C-Mn和MnMoNi钢)的一些实验数据一致. | 吕铮 R.G.Faulkner P.E.J.Flewitt | 2005 | 金属学报2005，41，1： | 3 |
| 2 | Determination of Neutron Irradiation-Induced Phosphorus Segregation on Grain Boundaries in a P-doped 2.25Cr1Mo Steel显示文摘Irradiation-induced impurity segregation to grain boundaries is one of the important radiation effects on materials.For this reason, phosphorus segregation to prior austenite grain boundaries in a P-doped 2.25Cr1Mo steel subjected to neutron irradiation is examined using field emission gun scanning transmission electron microscopy (FEGSTEM) with energy dispersive X-ray microanalysis (EDX). The steel samples are irradiated around 270 and 400℃, respectively.The irradiation dose rate and dose are ~1.05×10-8 dpa/s and ~0.042 dpa respectively for 270℃ irradiation, and 1.7×10-8 dpa/s and 0.13 dpa respectively for 400℃ irradiation. The FEGSTEM results indicate that there is no apparent phosphorus segregation during 270℃ irradiation but there is some during 400℃ irradiation. | ShenhuaSONG R.G.Faulkner P.E.J.Flewitt DongdongSHEN JingLIU ZexiYUAN | 2004 | Journal of Materials Science & Technology2004，20，1： | 1 |
| 3 | Modelling of Equilibrium Grain Boundary Solute Segregation under Irradiation显示文摘Both radiation-induced excess vacancies and solute-interstitials may enhance solute diffusion. The radiation-enhanced solute diffusion promotes the kinetic process of equilibrium segregation. This effect is especially considerable in the low temperature range. As a complement to modelling of radiation-induced non-equilibrium segregation, the radiationcreated vacancy and solute-interstitial-accelerated equilibrium grain boundary solute segregation were theoretically treated. The models were applied to phosphorus segregation in α-Fe subjected to neutron irradiation. | ShenhuaSONG R.G.Faulkner P.E.J.Flewitt LuqianWENG | 2005 | Journal of Materials Science & Technology2005，21，2： | 1 |

| 5 | GRAIN-BOUNDARY PRECIPITATION UNDER IRRADIATION IN DILUTE BINARY ALLOYS显示文摘Irradiation-induced grain boundary segregation of solute atoms frequently bring about grain boundary precipitation of a second phase because of its making the solubility limit of the solute surpassed at grain boundaries. Until now the kinetic models for irradiation-induced grain boundary precipitation have been sparse. For this reason, we have theoretically treated grain boundary precipitation under irradiation in dilute binary alloys. Predictions ofγ'-Ni3Si precipitation at grain boundaries ave made for a dilute Ni-Si alloy subjected to irradiation. It is demonstrated that grain boundary silicon segregation under irradiation may lead to grain boundaryγ'-Ni3 Si precipitation over a certain temperature range. | S.H.Song Z.X.Yuan J.Liu R.G.Faulkner | 2003 | Acta Metallurgica Sinica(English Letters)2003，16，5： | 0 |
| 6 | Hf对铁素体钢中辐照引起的晶间偏析的影响显示文摘1%Hf(质量分数)被注入E911钢中.利用250 keV的Ni离子在300℃辐照含Hf和不含Hf的E911钢,以研究Hf的添加对铁素体/马氏体钢中由辐照引起的偏析的影响.结果表明,Hf的添加抑制了晶界上P原子的富集和Cr原子的贫化.讨论和评估了Hf对自由迁移的缺陷数量的影响,结合一个辐照引起的非平衡偏析(RIS)模型以预测Hf对P,Cr等元素的晶界偏析行为的作用.对预测结果和实验数据作了比较. | 吕铮 R.G.Faulkner 坂口纪史 木下博嗣 高桥平七郎 P.E.J.Flewitt | 2006 | 金属学报2006，42，10： | 0 |
