Amorphous and Nanocrystalline Soft Magnetic Materials
Annealing of amorphous precursor alloys, with compositions (Fe,Co!88M7B4Cu1 ~M5Zr, Nb, Hf!, above their primary crystallization temperature results in the nanocrystallization of the ferromagnetic a8-FeCo phase. This work describes results of the characterization of these alloys, including morphological and chemical stability of the a8-FeCo phase, examination of alloy compositions, and developme...
متن کاملAmorphous and nanocrystalline materials for applications as soft magnets
This review seeks to summarize the recent developments in the synthesis, structural characterization, properties, and applications in the ®elds of amorphous, bulk amorphous, and nanocrystalline soft magnetic materials. Conventional physical metallurgical approaches to improving soft ferromagnetic properties have relied on the optimization of chemical and microstructural features. Within the las...

متن کاملAmorphous and Nanocrystalline High Temperature Magnetic Material for Pwr
We have used transmission electron microscopy (TEM) to observe the morphologies of ferrite nanoparticles synthesized using a radio frequency plasma torch. These nanoparticles were faceted, having cuboctahedral polygonal growth forms with exclusively the {111} and {100} type faces. A model for the critical nucleus shapes and the growth forms of small cuboctahedral particles is proposed consideri...
متن کاملNanocrystalline materials – Current research and future directions
Nanocrystalline materials, with a grain size of typically < 100 nm, are a new class of materials with properties vastly different from and often superior to those of the conventional coarse-grained materials. These materials can be synthesized by a number of different techniques and the grain size, morphology, and composition can be controlled by controlling the process parameters. In compariso...
