Abstract Scope Metal amorphous nanocomposite (MANC) soft magnetic materials are of current interest for power converters and motors. At higher frequencies, motors and converters can be reduced in size while maintaining equivalent power output. Conventional materials are inefficient at high frequency due to smaller electrical resistivities and inability to cast and roll to 10’s of μm thickness. MANC materials can exhibit higher efficiencies due to high resistivities and low anisotropies1–3. Here, Fe-Ni-based MANCs are investigated. For (FexNi1-x)80Nb4Si2B14 (25≤x≤80,) γ-FeNi is the primary crystallization product except for x=75, where α-FeNi forms. X-ray diffraction shows secondary crystallization products to be (FeNi)23B6. Mechanical properties, determined by strain annealing at 200 and 300 MPa on all compositions, show a maximum elongation of 57% at the (Fe60Ni40)80Nb4Si2B14 composition. The temperature dependence of elongation is determined for this composition as well. Finally, B-H loops are compared for both as-cast samples and strain annealed samples.
