Title:
HIGH-STRENGTH AND DUCTILITY MULTI-COMPONENT SOFT MAGNETIC ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/082723
Kind Code:
A1
Abstract:
Disclosed in the present invention are a high-strength and ductility multi-component soft magnetic alloy and a preparation method therefor. The high-strength and ductility multi-component soft magnetic alloy consists of the following components in atomic percentages: 32-45% of Fe, 24-29% of Co, 24-29% of Ni, 2.5-8% of Al, 1.5-3.5% of Ti, 1.0-5% of Ta, 0-2% of Nb, and 0-2% of Mo. The multi-component alloy matrix prepared by the present invention mainly presents the structural features of a face-centered cubic structure, has excellently matched strength and plasticity as well as relatively low coercive force and relatively high saturation magnetization, and can be made into important devices to be applied to the fields of power industry, automatic control, mobile communications, etc.
