| Abstract: | We present microscopic evidence of structural relaxation in the purely metallic glass Zr67Ni10Cu23 doped with 0.5 at.% of57Fe. The Mössbauer spectra under different heat treatments were analyzed by a six-parameter model. Two regimes of structural relaxation, irreversible and reversible relaxation, are clearly distinguished and the latter involves different atomic processes over different temperature regions. |
