| Abstract Scope |
Nanocrystalline soft magnetic alloys have demonstrated superior performance in a broad range of emerging magnetic component applications, with particular value in the medium frequency (1-50 kHz) and medium to high power (kW-MW) range. A number of emerging applications in space, aviation, and electrified transportation are increasing the demand for long-term stable, high performance operation in extreme environment applications approaching or even exceeding temperatures of 500C. With Curie temperatures approaching 1000C, Co- and FeCo-based nanocrystalline alloys show particular relevance for these applications however their capabilities for extended high temperature operation and corrosion resistance in extreme environment applications have not been investigated in sufficient detail. This presentation will highlight the various aspects of “stability” that must be considered and benchmarked, including microstructure, oxidation / corrosion resistance, and magnetic properties. An overview of recent progress targeting soft magnetic nanocrystalline alloys for T>500C will also be presented and future research directions will be discussed. |
