Notes:
The purpose of this research is to investigate the micro-mechanism of anelastic behavior ofmetallic glass. The changes of atomic arrangement in Cu50Zr50 metallic glass were observed directlyby EXAFS method during tensile deformation. The transmission-mode EXAFS measurementsaround Zr K-edge and Cu K-edge of the sample in various amounts of tensile deformation conditionswere done. The interatomic distance between Cu-Zr increased, and that between Zr-Zr decreasedsimultaneously, with the amount of tensile deformation increase of the sample at first stage ofdeformation. When the atomic distances reached to certain values respectively, they recovered to theinitial values of no tensile deformation condition at first stage, and then the atomic distances changedas same manner as the first stage of deformation, respectively. This is the first observation on thechange of atomic arrangement during tensile deformation of metallic glass
