Bulk Nanocrystalline Fe84Nb4W3B9 Alloy Prepared by Super-high-pressure Consolidation from Mechanically Alloyed Powders

摘要

Amorphous and nanocrystalline Fe-based alloys are technologically important materials due to their good magnetic properties and low cost. However, the appearances of the alloys obtained by melt spinning and sputtering techniques are limited to ribbon and strip, film, wire, and powders, which largely restricts their applications in many engineering devices in which big size and arbitrary shape are often necessary. Thus, generating bulk materials with good soft magnetic properties is of great interest.
