Magnetic permeability of ( Fe Co Ge ) 88 Zr 6 B 5 Cu 1 alloys: Thermal stability in a wide temperature range.
(AIP Publishing, 2008)
Temperature dependence, from room temperature up to 1000 K, of the initial permeability of Fe83−xCoxGe5Zr6B5Cu1 x=5 and 20 alloys at different stages of devitrification is reported. As nanocrystallization progresses, ...

Two Milling Time Regimes in the Evolution of Magnetic Anisotropy of Mechanically Alloyed Soft Magnetic Powders
(Elsevier, 2011)
The milling time evolution of magnetic anisotropy of ball milled powders can be described considering two regimes. First, for short milling times, the main factor affecting the magnetic behavior of the alloy is the ...

Evolution of Fe environments in mechanically alloyed Fe–Nb–(B) compositions
(Elsevier, 2014)
Nanocrystalline alloys of nominal composition Fe85Nb5B10 were produced by mechanical alloying from a mixture of elemental powders. Two commercial boron structures were used: amorphous and crystalline. In addition, a third ...

Partial substitution of Co and Ge for Fe and B in Fe-Zr-B-Cu alloys: microstructure and soft magnetic applicability at high temperature
(Elsevier, 2005)
The partial substitutions of Co for Fe and Ge for B are studied for a Fe83-xCoxZr6B10-yGeyCu1 alloy series (x = 0, 5 and 20; y = 0 and 5) as a possible way to enhance the high temperature applicability of NANOPERM alloys. ...

Study of the Induced Anisotropy in Field Annealed Hitperm Alloys by Mössbauer Spectroscopy and Kerr Microscopy
(Springer Nature, 2016)
Samples of Fe39Co39Nb6B15Cu1 alloy were nanocrystallized under zero field annealing (ZF) and transverse field annealing (TF) conditions. A reduction in coercivity for TF samples with respect to ZF sample (16 and 45 A/m, ...

Correction of the Shape Effect on Magnetic Entropy Change in Ball Milled Fe70Zr30 Alloys
(Elsevier, 2018)
The field dependence of the magnetic entropy change (ΔSM) after mechanical alloying of Fe70Zr30 composition starting from high purity powders is studied. Samples with different shapes and different crystalline fraction X ...

Influence of Ge addition on the magnetocaloric effect of a Co-containing Nanopermtype alloy.
(AIP Publishing, 2008)
The influence of the partial substitution of B by Ge on the magnetocaloric response of Fe78Co5Zr6B10Cu1 is studied. Ge addition produces a reduction in the temperature at which the peak entropy change takes place, as ...

Structural ordering and magnetic properties of arc-melted FeGa alloys
(Elsevier, 2007)
X-ray diffraction, Mössbauer spectrometry and magnetic properties have been performed on FeGa arc-melted binary alloys in order to study the compositional dependence of the structural ordering and magnetic properties of ...

Structural Relaxation in Fe(Co)SiAlGaPCB Amorphous Alloys
(Elsevier, 2014)
The structural relaxation of multicomponent Fe(Co)SiAlGaPCB amorphous alloys was investigated calorimetrically for annealed samples over a wide temperature range below the glass transition temperature. Upon heating, the ...

Nanocrystallization Kinetics Understood as Multiple Microprocesses Following the Classical Theory of Crystallization
(Elsevier, 2016)
In this work, we propose a model for using the classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) crystallization theory to analyze nanocrystallization processes as a set of multiple microprocesses. This model is based on the ...
