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

The effect of plastic deformation on the magnetic parameters of rapid-quenched nanostructured Co 66 Fe 4 Nb 2.5 Si 12.5 B 15 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.
