Mg-Mo series Fe-based amorphous alloy ribbon and preparation method thereof

Abstract

The invention discloses an Mg-Mo series Fe-based amorphous alloy ribbon. The Mg-Mo series Fe-based amorphous alloy ribbon is characterized in that the Mg-Mo series Fe-based amorphous alloy ribbon comprises 7-9% of Mg, 2-3% of Mo, 0.9-1.2% of V, 0.04-0.06% of Ta, 5.8-6.4% of Zn, 2.1-2.3% of Ni, 0.04-0.06% of W, 0.12-0.16% of Tm, and the balance Fe. A preparation method of the amorphous ribbon is similar to preparation methods of routine amorphous ribbons, treats Mg-Mo as a basic doping material, allows other components of V, Ta and the like to be added, optimizes the heat treatment technology, and obviously improves the stress distribution of the amorphous alloy ribbon, so the amorphous alloy material has an excellent toughness, a good plasticity, an excellent soft-magnetic performance and a good amorphous formation capability, and can be widely used for various amorphous ribbon ring materials.

Description

technical field [0001] The invention relates to the field of magnetic functional materials, in particular to an iron-based amorphous alloy thin strip with excellent performance and a preparation method thereof, which can be widely used in various amorphous thin strip ring materials. Background technique [0002] The existing transformer magnetic core is mostly made of silicon steel sheet, although it has a relatively high saturation magnetic induction (2.0T), but the intermediate frequency loss is large and the energy consumption is high. Amorphous alloys are beginning to be used as amorphous thin strip ring materials for transformers, but their saturation magnetic induction is smaller than that of silicon steel, and their applications are limited. Therefore, it is necessary to develop an amorphous alloy thin strip material with high saturation magnetic induction and low intermediate frequency loss. The focus of research on amorphous thin strip ring materials for transformer...
