Multicycle electric pulse loading of amorphous cobalt- and iron-based alloys

The effect of electric current pulses on the mechanical characteristics of Co and Fe-based ribbon amorphous alloys is investigated. It is shown that the alloy tensile strength and the maximal pulse amount for destruction decrease linearly growth current density. The dependences between the $\sigma$ tensile strength of current-induced parallel magnetized materials and $\varepsilon$ relative sample deformation is noticed, and micro-bursts of mechanical stress appear at mentioned conditions. The manifestation of microbursts may be associated with a magnetocaloric effect.
