Influence of γ-irradiation on Properties of Amorphous Fe₇₈B₁₃Si₉ Alloy Studied by Mössbauer Spectroscopy and Bending Test

The influence of γ-irradiation on properties of METGLAS 2605S2 and FC3-1 Fe₇₈B₁₃Si₉ has been investigated by Möissbauer spectroscopy and bending test. The ductility and orientation of magnetization were changed by γ-irradiation. They probably correlated with the change of microscopic free volume and release of stress in the ribbon, respectively.
