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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
