摘要：

The structural and magnetic properties of amorphous Fe-87 - yB13Cuy (y = 0 to 1.5) annealed with a range of heating rates (a) up to 150 K/s were investigated. The lowest coercivity (H-c) for Fe87B13 after crystallization shows a dramatic decrease from 174 A/m to 6.7 A/m when a is increased from 1.7 K/s to 150 K/s. The coercivity of Fe-87 - yB13Cuy annealed at 150 K/s is reduced by Cu addition and H-c = 3.0 A/m is obtained at y = 1.5. Nano structures with a grain size of 15 to 20 nm were evident in transmission electron micrographs from these rapidly annealed alloys. (C) 2017 Acta Materialia Inc. Published by Elsevier Ltd.
