Microstructural analysis on reactor pressure vessel steel using the XAFS method

Iwata, Keiko; Takamizawa, Hisashi; Nishiyama, Yutaka; Shimoyama, Iwao; Okamoto, Yoshihiro; Iwase, Akihiro*; Kojima, Hiroshi*; Mayumi, Ren*

no journal, , 

Microstructure analysis on reactor pressure vessel steel was conducted by using X-ray absorption fine structure (XAFS) method, where local atomic structures and coordination number around selected atoms are obtained. In our presentation, microstructural changes of thermally aged or electron-irradiated samples will be discussed.

Microstructure analysis on thermally aged stainless overlay cladding using X-ray absorption

Iwata, Keiko; Takamizawa, Hisashi; Ha, Yoosung; Okamoto, Yoshihiro; Shimoyama, Iwao; Kojima, Hiroshi*; Mayumi, Ren*; Iwase, Akihiro*; Nagai, Yasuyoshi*; Nishiyama, Yutaka

no journal, , 

Microstructure analysis for thermally aged stainless overlay cladding was conducted by using X-ray absorption. X-ray absorption fine structure analysis was adapted, which was possible to obtain the average information of a material and to identify the bond length and chemical state by the selected atoms. In this study, changes of coordination number and bond length around the Mn atom were recognized.
