Influence of Nb and Mo Substitution on the Structure and Magnetic Properties of a Rapidly Quenched FeCoCuB Alloy.

The importance of amorphous and nanocrystalline Fe-based soft magnetic materials is increasing annually. Thus, characterisation of the chemical compositions, alloying additives, and crystal structures is significant for obtaining the appropriate functional properties. The purpose of this work is to present comparative studies on the influence of Nb (1, 2, 3 at.

Effect of Co Substitution and Thermo-Magnetic Treatment on the Structure and Induced Magnetic Anisotropy of FeCoNbBP Nanocrystalline Alloys.

In the present work, we investigated in detail the thermal/crystallization behavior and magnetic properties of materials with FeCoNbBP (x = 0, 5, 10, 15 and 20 at.%) composition. The amorphous ribbons were manufactured on a semi-industrial scale by the melt-spinning technique.

The Structure and Magnetic Properties of Rapidly Quenched FeNiNbSiB Alloy.

The complex structural and magnetic studies of the annealed rapidly quenched Cu-free FeNiNbSiB alloy (metallic ribbons form) are reported here. Based on the calorimetric results, the conventional heat treatment process (with heating rate 10 °C/min and subsequent isothermal annealing for 20 min) for wound toroidal cores has been optimized to obtain the least lossy magnetic properties (for the minimum value of coercivity and magnetic core losses at 50 Hz). For optimal conditions, the complex permeability in the 10-10 Hz frequency range together with core power losses obtained from magnetic induction dependence up to the frequency of 400 kHz was successfully measured.

Fe-Co-B Soft Magnetic Ribbons: Crystallization Process, Microstructure and Coercivity.

In this work, a detailed microstructural investigation of as-melt-spun and heat-treated FeCoB ribbons was performed. The as-melt-spun ribbon was predominantly amorphous at room temperature. Subsequent heating demonstrated an amorphous to crystalline α-(Fe,Co) phase transition at 403 °C.

Influence of Cu Content on Structure and Magnetic Properties in FeCuB Alloys.

Influence of Cu content on thermodynamic parameters (configurational entropy, Gibbs free energy of mixing, Gibbs free energy of amorphous phase formation), crystallization kinetics, structure and magnetic properties of FeCuB (x = 0, 0.4, 0.55, 0.

Effect of Co Substitution on Crystallization and Magnetic Behavior of FeCoCuB Metallic Glass.

The effects of Co for Fe substitution on magnetic properties, thermal stability and crystal structure of FeCoCuB (x = 0, 2.5, 5, 7.5, 10) melt spun amorphous alloys were investigated.
