Impact of duration of holding of various-composition amorphous ribbons within the 0.17 T magnetic field (MF) on their microhardness is investigated for the first time. Ribbons are held in the air at room temperature. Non-monotonic dependence of microhardness on holding duration in MF for samples of amorphous metal alloys (AMA) is revealed. Such a feature manifests itself for both magnetic and non-magnetic AMA. Long-term holding in MF results in strengthening of AMA. As suggested, the detected magneto-mechanical effect is caused by transition of the amorphous alloy under MF action into a new structural state with different short-range order parameters and level of internal stresses.

Keywords: amorphous metal alloys, magnetostatic field, microhardness, magnetomechanical effect.
