| Abstract Scope |
Nanocrystalline soft magnetic alloys have demonstrated superior performance in a range of applications, with particular value in the medium frequency (1-50 kHz) and medium to high power (kW-MW) range. 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 relevance for these applications however their capabilities for extended high temperature operation and corrosion resistance in extreme environment applications have not been investigated in detail. This presentation will highlight various aspects of “stability” that must be considered and benchmarked, including microstructural stability, oxidation / corrosion resistance, and magnetic properties. An overview of recent experimental progress targeting soft magnetic nanocrystalline alloys for T>500C will also be presented and future research directions will be discussed. |
