Abstract: A high-strength and tough multi-component soft magnetic alloy and preparation method thereof are provided. The high-strength and tough multi-component soft magnetic alloy is composed of the following components in atomic percentage: Fe 32-45%, Co 24-29%, Ni 24-29%, Al 2.5-8%, Ti 1.5-3.5%, Ta 1.0-5%, Nb 0-2%, and Mo 0-2%. The multi-component alloys prepared by the present invention exhibit a face-centered cubic structure of the matrix, featured with high strength, high ductility, low coercivity and relatively high saturation magnetization. These properties make it suitable for manufacturing critical components for applications in industries such as electrical engineering, automatic control, mobile communications, and others.

Abstract: A type of high-strength and ductile multicomponent precision resistance alloys and fabrication methods thereof are provided. The alloys are composed of the following components by atomic percentage: Ni 45-60%, Cr 15-30%, Fe 5-20%, Al 5-15%, Mn 3-5%, Cu 0.2-3%, Si 1-5%. Particularly, the sum of the atomic percentages of Mn, Cu and Si is ?13% and ?4.2%, the sum of the atomic percentages of Ni, Cr, Fe and Al is ?70% and ?95.8%, and the sum of the atomic percentages of all the components is 100%. The multicomponent alloys prepared by the methods exhibit face-cantered cubic matrix and possess high strength and good ductility; further, they have high resistivity and excellent resistivity stability in wide temperature ranges below 773 K.
