Abstract

The invention discloses an iron-based amorphous alloy material. The iron-based amorphous alloy material comprises the following components in percentage by weight: 89.6%-92.4% of Fe, 0.08%-0.19% of Cr, 0.02%-0.05% of Cu, 3.8%-5.2% of Si, 2.1%-3.2% of B, 0.05%-0.16% of C and 0.33%-0.82% of Ti.

Description

technical field [0001] The invention relates to the field of material science, in particular to an iron-based amorphous alloy material. Background technique [0002] The general amorphous alloy material has high magnetic permeability due to its high resistivity and no crystal anisotropy. It is an excellent magnetic material and can be widely used in transformers, transformers, sensors and other fields. However, the manufacturing method of amorphous alloy materials generally adopts arc melting, etc., which has many process steps, consumes a lot of energy, is costly, and is not environmentally friendly. [0003] The main raw materials of amorphous alloy materials are iron, silicon, boron, etc. Usually, the quenching technology of quenching and solidifying the master alloy from the molten state is used to prepare amorphous alloy thin strips, which are cast into thin strips by rapidly solidifying them. The thickness of the ribbon is less than a quarter of that of a human hair, ...
