Microstructure and magnetic properties of Fe85−xCoxNb5B8P2 high temperature nanocrystalline alloys

摘要: Abstract A new family of Fe–Co based high temperature nanocrystalline alloy was developed using Fe 85− x Co Nb 5 B 8 P 2 as a precursor amorphous material, which can be cast in air. The sample presented flat hysteresis loop with excellent frequency and behaviour. material crystallizes at relative low (400°C), relatively activation energy (2.7 eV) for =20. annealed 500°C shows independent soft magnetic properties (Hc around 40 A/m, permeability 450 up to 1 MHz) the applied annealing temperature.
