Effect of Plastic Deformation on the Magnetic Properties of Rapid-Quenched Cobalt-Based Metal Wires

Abstract

The effect of plastic deformation on the magnetic parameters of rapid-quenched nanostructured Co₆₆Fe₄Nb_2.5Si_12.5B₁₅ wires was established for the first time, as well as their sensitivity to tensile stresses. Plastic deformation changes magnetic anisotropy induced by the rapid quenching of cobalt-based metal wires, and, as a consequence, determines their magnetic parameters. Remanence is a characteristic that is most sensitive to plastic deformation. A conclusion is drawn that plastic deformation of wires leads to an increase in magnetostriction constant.
