Structural-Scale Levels of Deformation of Quasi-Amorphous Soft Magnetic Alloy Ribbons

Abstract—The structure, deformation behavior, and tensile properties of soft magnetic alloy 2NSR, 30KSR, and 84KKhSR ribbons produced by melt spinning are studied. The ultimate tensile strength of the ribbons is shown to exceed 1000 MPa at a small relative elongation ε ≈ 1%, and the elastic modulus is 100 GPa. Strain component distribution fields are constructed and analyzed. The characteristic structural-scale levels of deformation in the alloy ribbons are discussed.
