The effect of exposure of the amorphous alloy Fe$_{73.0}$Cu$_1$Nb$_{3.0}$Si$_{15.8}$B$_{7.2}$ in a weak magnetic field (0.2 T) on mechanical properties and fractography of the fracture surface is studied. As found, the micromechanical properties of the alloy under study undergo nonmonotonic changes depending on the exposure time in a magnetic field. With long exposures in a magnetic field, microhardness and tensile strength increase. The state of the fracture surface of the ribbons also changes relative to the initial one. A conclusion about the possible physical nature of the established magnetomechanical effects is made.

Key words: amorphous alloys, magnetic field (MF), magnetomechanical effect, ductility increase, hardening.
