Abstract

Elemental analysis study of the positron affinitive nano-structures in materials by coincidence Doppler broadening method are presented: (1) defect free Cu nano-clusters embedded in Fe, (2) nano-voids in Fe covered with Cu atoms, and (3) solute clusters (GP zones) in Al alloys (Al-Ag and Al-Zn). By utilizing positron trapping not only in vacancy-type defects but also positron affinitive, defect-free nano-clusters embedded in materials, unique and exclusive information, such as defect structure, coherency, chemical composition, and so on, on the trapping sites can be obtained.
