Milling effects on magnetic properties of melt spun Fe-Nb-B alloy
(AIP Publishing, 2014-02-25)
Fe75Nb10B15 amorphous ribbons were grinded via ball milling to produce powder samples preserving the amorphous microstructure. A continuous increase of the Curie temperature with the milling time is observed ...

A procedure to extract the magnetocaloric parameters of the single phases from experimental data of a multiphase system.
(AIP Publishing, 2014)
In this work, we propose a method to extract the individual parameters that describe the field dependence of magnetic entropy change of each phase in a multiphase system. This method makes use of the scaling laws of the ...

Extracting the composition of nanocrystals of mechanically alloyed systems using Mössbauer spectroscopy
(Elsevier, 2014)
Determining the composition at the nanoscale generally requires the use of experimental techniques such as 3D atom probe or nanoanalysis, which have limited availability, involve high economic cost and, moreover, imply ...

Magnetocaloric effect of Co62Nb6Zr2B30 amorphous alloys obtained by mechanical alloying or rapid quenching
(2014)
Amorphous samples of nominal composition Co62Nb6Zr2B30 have been prepared using mechanical alloying (MA) and rapid quenching (RQ) techniques. Differences appear in Curie temperature and the phases developed after ...

Influence of the demagnetizing factor on the magnetocaloric effect: Critical scaling and numerical simulations
(AIP Publishing, 2014)
In recent years, the magnetocaloric effect is studied not only for the search of potential magnetic refrigerant materials but also for the analysis of critical phenomena. In both cases, the demagnetizing field might have ...

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 ...

Crystallization kinetics and soft magnetic properties in metalloid-free (Fe, Co)90Zr10 amorphous and nanocrystalline alloys
(Elsevier, 2014)
Microstructure and magnetic properties of metalloid-free (Fe100- xCox)90Zr10 amorphous and nanocrystalline alloys were characterized. Devitrification of these amorphous alloys occurs in two overlapped transformations leading ...
