Prof. Koji INOUE Assist. Prof. Peng SONG Towards Revealing Irradiation-Induced Defects and Controlling Their Function We are studying defects, sub-nanoscale precipitates and interface segregations of impurity/solute atoms in materials. Our target extends from nuclear materials such as reactor pressure vessel steels and shroud stainless steels to semiconductors such as silicon and germanium. We employ positron annihilation, atom probe tomography, electron microscope, etc. By combining various theoretical calculations with the above experiments, we are clarifying the formation and microscopic structures of these defects, precipitates and interface segregations. nuclear materials, semiconductors, positron, atom probe tomography, electron microscopy 3D structural – chemical analyses by combining electron tomography by STEM with atom probe tomography and positron annihilation spectroscopy enable to directly reveal relationship between formation of irradiation induced fine defects and impurity segregation/clustering. Elemental distribution in high entropy alloy obtained by atom probe tomography. Fine phase separation is obtained. http://wani.imr.tohoku.ac.jp/（Japanese text only） Department of Quantum Science and Energy Engineering, Graduate School of Engineering About IMRAbout IMRDirector’s
