Amorphization and evolution of magnetic properties during mechanical alloying of Co62Nb6Zr2B30: dependence on starting boron microstructure
(Elsevier, 2014)
Co62Nb6Zr2B30 composition was mechanically alloyed using three different types of boron powders in the starting mixture: crystalline β-B, commercial amorphous B and optimized amorphous B via ball milling. Using optimized ...

Influence of Hot Compaction on Microstructure and Magnetic Properties of Mechanically Alloyed Fe(Co)-based Amorphous Compositions
(Elsevier, 2015)
Amorphous Fe75Nb10B15 and (Fe70Co30)75Nb10B15 alloys were prepared by mechanical alloying from the elemental constituents and hot compacted at different temperatures within the supercooled liquid region. After compaction, ...

Analysis of magnetocaloric effect of ball milled amorphous alloys: Demagnetizing factor and Curie temperature distribution
(Elsevier, 2015)
The magnetocaloric effect (MCE) has been measured for an amorphous mechanically alloyed (MA) Co62Nb6Zr2B30. It is demonstrated that sample shape must be taken into account for a correct interpretation of the results, ...

Metastable Soft Magnetic Materials Produced by Mechanical Alloying: Analysis Using an Equivalent Time Approach
(Springer Nature, 2013)
Mechanical alloying, a ball milling technique where heterogeneous starting powders are homogenized and alloyed, has become a versatile technique for the production of metastable microstructures: nanocrystalline and/or ...

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 ...

Analysis of the Mechanically Alloyed Fe85-Nb5-B10 Powder Using a Non-unique Lattice Parameter
(Elsevier, 2008)
X-ray diffraction patterns of mechanically alloyed Fe85Nb5B10 powder were fitted using whole powder pattern decomposition procedure to resemble the presence of α-Fe type crystals with different Nb content. To do so, a ...
