Title:
IRON-BASED AMORPHOUS ALLOY HAVING LOW STRESS SENSITIVITY, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/227792
Kind Code:
A1
Abstract:
An iron-based amorphous alloy. The iron-based amorphous alloy comprises components FeaBbSic, a, b and c respectively indicating atomic percentage contents, 79.5≤a≤82.5, 11.0≤b≤13.5, 6.5≤c≤8.5, and a+b+c=100. An iron-based amorphous alloy strip is obtained by means of a rapid quenching method in which a single roller is used. Because the iron-based amorphous alloy has higher saturated magnetic induction density, a higher amorphous formation capability and lower stress-resistance sensitivity, the iron-based amorphous alloy can be used as an iron core material for preparing a power transformer, a power generator and an engine; in addition, due to the low stress sensitivity of the iron-based amorphous alloy, the sudden short-circuit resistance capability of an amorphous transformer can be improved when the power transformer is prepared.
