Three kinds of Fe-based model alloys, Fe-0.018 atomic percent (at.%) Cu, Fe-0.53at.%Cu, and Fe-1.06at.%Cu were irradiated with 2 MeV electrons up to the dose of 2$$times$$10$$^{-5}$$ dpa at 250$$^{circ}$$C. After the irradiation, the increase in Vickers hardness and the decrease in electrical resistivity were observed. The increase in hardness by electron irradiation is proportional to the product of the Cu contents and the square root of the electron dose. The decrease in electrical resistivity is proportional to the product of the square of Cu contents and the electron dose. Cu clustering in the materials with electron irradiation and thermal aging was observed by means of the three dimensional atom probes (3D-AP). The change in Vickers hardness and electrical resistivity is well correlated with the volume fraction of Cu clusters.

Use of high energy ions for the mechanistic study of irradiation embrittlement in pressure vessel steels using Fe-Cu model alloys

Morita, Kenji*; Ishino, Shiori*; Tobita, Toru; Chimi, Yasuhiro; Ishikawa, Norito; Iwase, Akihiro

Journal of Nuclear Materials, 304(2-3), p.153 - 160, 2002/08

 Times Cited Count:13 Percentile:65.26(Materials Science, Multidisciplinary)

To study the mechanism of irradiation embrittlement in pressure vessel alloys, we performed high energy ion irradiation experiments using FeCu model alloys. The dependences of Vickers hardness change by irradiation on ion fluence, irradiation temperature and Cu content were discussed.
