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 ...

Grinding and particle size selection as a procedure to enhance the magnetocaloric response of La( Fe, Si)(13) bulk samples
(Elsevier, 2017-05)
The magnetocaloric effect of La(Fe,Si)13 samples deteriorates with the presence of secondary phases. However, it is highly challenging to produce single phase samples by conventional procedures and purification requires ...

Influence of Co addition on the magnetocaloric effect of FeCoSiAlGaPCB amorphous alloys
(2006)
The FeCoSiAlGaPCB alloys can be prepared as bulk amorphous materials, with outstanding mechanical properties and increased electrical resistivity. These features can be beneficial for their application as a magnetic ...

Relationship between mechanical amorphization and boron integration during processing of FeNbB alloys
(Elsevier, 2014)
Fe75Nb10B15 alloys were prepared by mechanical alloying using different boron powders (crystalline B, commercial amorphous B, optimized amorphous B and intermetallic FeB) in the initial mixture, in order to study the ...

Mössbauer study of FeCoSiAlGaPCB amorphous alloys
(2004)
A Mössbauer spectrometry and magnetic study have been performed on FeCoSiAlGaPCB amorphous alloys in order to get information about the variations in the atomic short range order with the substitution of Fe by Co. The ...

Magnetic and Structural Characterization of Mo-Hitperm Alloys with Different Fe/Co Ratio
(Elsevier, 2011)
The influence of the Co content on the microstructure and magnetic behaviour of a series of amorphous and nanocrystalline (FeCo) 79Mo8Cu1B12 alloys is reported. Changes in the magnetic properties provoked by the microstructural ...

Study of Phases Evolution in High-coercive MnAl Powders Obtained Through Short Milling Time of Gas-atomized Particles
(Elsevier, 2017)
Gas-atomized Mn54Al46 particles constituted nominally of only ε- and γ2-phases, i.e. no content of the ferromagnetic L10-type τ-phase, have been used to study the evolution of phases during short time of high-energy milling ...
