Extension of the Classical Theory of Crystallization to Non-isothermal Regimes: Application to Nanocrystallization Processes
(Elsevier, 2012)
The non-isothermal kinetics of primary crystallization processes is studied from numerically generated curves and their predictions have been tested in several nanocrystallization processes. Single processes and transformations ...

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 ...

Structure and magnetic properties of Fe–Nb–B amorphous/nanocrystalline alloys produced by compaction of mechanically alloyed powders
(AIP Publishing, 2010)
Mechanical alloying of Fe75Nb10B15 and Fe85Nb5B10 systems has been performed from an initial mixture of elemental powders. A bcc supersaturated solid solution is developed during milling for both alloys. However, Fe75Nb10B15 ...

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 ...

Role of starting phase of boron on the mechanical alloying of FeNbB composition
(Elsevier, 2013)
Mechanical alloyed Fe75Nb10B15 systems, prepared with crystalline or commercial amorphous boron and a similar composition with the same Fe/Nb ratio but no boron, have been studied as a function of milling time in the aim ...

Preferential Co Partitioning to α-Fe in Nanocrystalline CoFeNbB Alloys by Mn Addition
(Elsevier, 2009)
Influence of Mn addition on the microstructure and hyperfine parameters of amorphous and nanocrystalline Co60(FeMn)18Nb6B16 alloys has been studied. Although Mn addition does not yield significant differences in crystallization ...

Ball milling as a way to produce magnetic and magnetocaloric materials: a review
(Springer Nature, 2017)
Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an ...
