Fe-6at.%合金的显微组织和化学变化用原子探针层析成像技术研究了Cr二元模型合金在290 ℃、1.82dpa中子辐照下的形貌。辐照后，Si和Cr被发现偏析位错环，这是分析的数量密度，尺寸和惯习面。晶界化学之间的定量比较收到和中子辐照合金。结果进行了讨论的背景下，平衡偏析，辐射增强扩散，和/或辐射诱导的偏析。(C)2014爱思唯尔有限公司版权所有。
The microstructural and chemical changes in a Fe-6 at.%Cr binary model alloy neutron irradiated to 1.82 dpa at 290 degrees C were investigated using atom probe tomography. After irradiation, Si and Cr are found segregated to dislocation loops, which were analyzed in terms of number density, size, and habit plane. Grain boundary chemistry was quantitatively compared between the as-received and the neutron irradiated alloys. The results are discussed in the context of equilibrium segregation, radiation-enhanced diffusion, and/or radiation induced segregation. (C) 2014 Elsevier B.V. All rights reserved.
