Abstract

In this overview we report on our recent investigations on processing of nanostructured γ-Ni-Fe alloy powder for its magnetic applications and suggest a new processing route for fabricating bulk nanostructured γ-Ni-Fe materials. Nanostructured γ-Ni-Fe alloy agglomerate powder having 20 nm in average grain size has been developed by hydrogen co-reduction of ball-milled powder mixture of nickel- and iron oxide. Regarding the bulk processing, two processing routes of intrinsic- and extrinsic-type are suggested; the intrinsic route is for processing nanostructured γ-Ni-Fe alloy bulk from the powder, and the extrinsic one is for fabricating γ-Ni-Fe nanoalloy particle dispersed ceramic- or polymer composite materials. The magnetic properties of these bulk materials according to their promising applications have been investigated depending on processing routes and discussed in association with chemical property and microstructure.
