Evolution of structure, microstructure and hyperfine properties of nanocrystalline Fe50Co50 powders prepared by mechanical alloying

Preparation and characterization of Fe50Co50 nanostructured alloy

“…The mean crystallite size was estimated by the Scherrer formula [7], taking into account the diffraction peak integral width calculated from the diffraction peaks refinement software GSAS. [1][2][3][4][5][6]. The powder size distribution and the particles shape are not uniform, as indicated by N. Yepes [8].…”

“…These alloys exhibit high saturation magnetization and high Curie temperatures [1], that make them potential candidates for the high temperatures applications such as new generation turbine engines as well as in recording media [2]. In particular the Fe 50 Co 50 alloy has a considerably large permeability, low magnetocrystalline anisotropy and low electrical resistivity [3]. All these properties are shown to be superior at the nanoscale.…”

“…This method is an intensive energy process of mechanical grinding for the preparation of alloyed powders. It involves a repeated fracturing and welding of particles, leading to size reduction of nanometer scale [3]. Nanostructured Fe 50 Co 50 alloys prepared by high energy mechanical alloying method at different milling times and characterized by SEM and XRD have been reported in the literature [1][2][3][4][5][6].…”

Magnetic Properties of Sintered Fe_{50}Co_{50} Powder Cores

“…Fe-Co soft magnetic alloys have low coercivity, low hysteresis loss, low eddy current loss, high permeability, high saturation magnetization, and high Curie temperature. In particular Fe 50 Co 50 alloy has a considerably large permeability, low magnetocrystalline anisotropy and low electrical resistivity [3].…”

“…The advantage of this process technology is that the powder can be produced in large quantities and the processing parameters can be easily controlled [4]. Some researches concerning Fe-Co powders system produced by mechanical milling were reported in [3,[5][6][7]. * corresponding author; e-mail: denisa.oleksakova@tuke.sk…”
