本研究的目的是研究热时效Fe-Cu合金的内摩擦（IF）行为，这些合金是模拟核反应堆压力容器（RPV）钢辐照脆化的模型试样。Fe-1wt板形试样。% Cu合金在1123K处淬火，在773K处热时效103min。采用自由共振弯曲振动法在无磁场条件下测量试样的中频。磁滞回线和电导率也进行了测量。热老化过程中频值、迟滞损耗和电导率均增大，表明中频特性与Cu溶质原子耗竭引起的电磁涡流损耗变化密切相关。这项研究证明了中频测量作为辐照RPV钢降解过程无损表征工具之一的应用可能性。
The purpose of this study is to investigate the internal friction (IF) behaviour of thermally aged Fe–Cu alloys that are model specimens simulating for the irradiation embrittlement of nuclear reactor pressure vessel (RPV) steels. Plate-shaped specimens of Fe–1wt.% Cu alloy were quenched from 1123K and thermally aged at 773K for 103min. The IF of the specimens was measured without magnetic field using the free resonant bending vibration method. Magnetic hysteresis loops and conductivity were also measured. The IF value, hysteresis loss, and conductivity increased under thermal aging, which suggests that the IF characteristics are closely related to the change of electromagnetic eddy-current loss due to the depletion of Cu solute atoms. This study demonstrates the possibility of the application of IF measurement as one of the tools for nondestructive characterization of degradation processes of irradiated RPV steels.
