DOI:
https://doi.org/10.3365/KJMM.2017.55.5.328
Abstract
In this study, the effect of the crystalline structure on the magnetic properties of Fe-based amorphous powder is investigated. The Fe-B-P-C-Nb-Hf amorphous powder with excellent soft magnetic properties is prepared via gas-atomization, and the atomized amorphous powder is annealed in order to generate a small amount of nanosized crystallites in.....
