Title:
FE-BASED AMORPHOUS NANOCRYSTALLINE ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/183909
Kind Code:
A1
Abstract:
The present description relates to the technical field of magnetic materials, and in particular to a Fe-based amorphous nanocrystalline alloy and a preparation method therefor. The Fe-based amorphous nanocrystalline alloy comprises the components of which elements have an atomic percent as shown in formula Fe(100-a-b-c-d-e-f)BaSibPcCdCueNbf, wherein 8≤a≤12, 0.2≤b≤6, 2.0≤c≤6.0, 0.5≤d≤4, 0.6≤e≤1.3, 0.6≤f≤0.9, and 1≤e/f≤1.4. The Fe-based amorphous nanocrystalline alloy has good magnetic performance, high thermal performance and a wide crystallization temperature range, and is convenient for industrial production.
