Title:
Fe-BASED ALLOY, CRYSTALLINE Fe-BASED ALLOY ATOMIZED POWDER, AND MAGNETIC CORE
Document Type and Number:
WIPO Patent Application WO/2019/031463
Kind Code:
A1
Abstract:
This Fe-based alloy is used for production of crystalline Fe-based alloy atomized powder, and has the alloy composition represented by a composition formula (1). In the composition formula (1), a, b, c, d, e, and α satisfy: 0.1 ≤ a ≤ 1.5; 13.0 ≤ b ≤ 15.0; 8.0 < c < 12.0; 0.5 ≤ d < 4.0; 0 ≤ e ≤ 2.0; 10.0 < c + d < 13.5; 0 ≤ α ≤ 0.9; and 71.0 ≤ 100 – a – b – c – d – e ≤ 74.0. Composition formula (1): Fe100-a-b-c-d-eCuaSibBc(Mo1-αNbα)dCre
