Amorphous and Nanocrystalline High Temperature Magnetic Material for PWR

Abstract

The initial charge of the DUST Program was to provide technical support to the development of inductive components for power electronics and integrated circuits where the driving forces for future improvement are size, frequency, and temperature. The CMU program was charged with examining amorphous and nanocomposite materials for inductive components. For these magnetic components the following figures of merit were identified for new materials development: 1) Induction: 1 to 2 T (5 to 10 times that of conventional ferrites at room temperature); 2) Frequency: 200 kHz to 1 MHz; 3) Temperature: 200 deg C and above. The goals of the DUST project were to develop composition, structure, and magnetic properties relationships in three areas for use in inductive components. These three areas of pursuit were: 1) amorphous precursors to HITPERM materials; 2) Fe-based amorphous materials; 3) HITPERM powders. The HITPERM materials are now felt to be competitive with Fe-based Metglas materials in terms of losses, while offering higher inductions and better high temperature magnetic properties.
