On the use of JMAK theory to describe mechanical amorphization: a comparison between experiments, numerical solutions and simulations
(MDPI, 2018)
The kinetics of amorphization during ball milling is generally analyzed using two different approaches: the classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory and Delogu and Cocco’s model for which a region ...

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, ...

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 ...

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 ...
