FeCo-BASED SOFT MAGNETIC NANOCRYSTALLINE ALLOYS

The influence of microstructure on the magnetic properties is studied in series of of FeCoNbB, FeCoZrB and FeCoMoBCu amorphous and nanocrystalline alloys with different amount of crystalline phase.V arious thermomagnetic treatments have been used in order to tailor the soft magnetic characteristics of these alloys for potential applications. We report on a beneficial effect of both longitudinal...

Surface Features of Nanocrystalline Alloys

Nanocrystalline alloys are prepared by controlled annealing of metallic glass precursors. The latter are obtained by rapid quenching of a melt on a rotating wheel. This process leads to structural deviation of the produced ribbons’ surfaces. Structural features of as-quenched and thermally annealed 57Fe81Mo8Cu1B10 ribbons were studied employing Conversion Electron Mössbauer Spectrometry (CEMS) ...

Oxidation Resistance of Nanocrystalline Alloys

Design of stable nanocrystalline alloys.

Nanostructured metals are generally unstable; their grains grow rapidly even at low temperatures, rendering them difficult to process and often unsuitable for usage. Alloying has been found to improve stability, but only in a few empirically discovered systems. We have developed a theoretical framework with which stable nanostructured alloys can be designed. A nanostructure stability map based ...
