Thermal and Microstructural Dependence of the Initial Permeability of Co60Fe18Nb6(B,Cu)16 Alloys
(Elsevier, 2007)
The thermal and microstructural dependence of the initial permeability of Co60Fe18Nb6B16-yCuy (y = 0, 1) alloys have been studied. The comparison of kinetics and microstructural data of the two compositions indicate the ...

Instantaneous growth approximation describing the nanocrystallization process of amorphous alloys: A cellular automata model
(Elsevier, 2008-07)
A cellular automata simulation based on an instantaneous growth approximation is developed to model the nanocrystallization kinetics. In this frame, the time required for a nucleus to grow up to its maximum size is ...

Thermal and Microstructural Stability of the Soft Magnetic Fe60Co18Nb6B15Cu1 alloy
(Elsevier, 2007)
Temperature evolution of the coercivity of nanocrystalline samples of Fe60Co18Nb6B15Cu1 alloy with different crystalline fractions was measured from room temperature up to 690 K. Although room temperature coercivity increases ...

High Temperature Coercivity of Nb-containing HITPERM Alloys: Effect of Cu Addition
(Elsevier, 2008)
Hysteresis loops of nanocrystalline samples of Fe39Co39Nb6B16 - yCuy (y = 0, 1) HITPERM-type alloys were measured from room temperature up to 773K. The alloy with Cu shows a nearly constant value of coercivity (∼ 135A/m) ...
