Structure and properties of Fe-Fe2B cermets
Journal of Materials Science, 1992The possibilities of producing Fe-Fe2B cermets as a result of sintering the pure elements Fe and B in a vacuum have been analysed. Attempts at sintering in the solid phase and with the participation of the liquid phase, the Fe-Fe2B eutectic, have been made.

Short-range atomic order in Fe2B powders
The Physics of Metals and Metallography, 2007The possibility of application of a local atomic displacement (LAD) model for describing the mechanism of formation of a low-field part (H hf ≤ 23.6 T) of a hyperfine-field distribution P(H) in a Fe2B alloy at early stages of grain refinement has been investigated. It has been found that the appearance of Mossbauer contributions,

Mechanochemically synthesized Fe2B nanoparticles embedded in SiO2 nanospheres
Ceramics International, 2018Abstract This study reports on the preparation of diiron boride (Fe 2 B) powders via mechanochemical synthesis (MCS) followed by a purification step and on the embedment of pure Fe 2 B nanoparticles into silica (SiO 2 ) nanospheres. Fe 2 O 3 , B 2 O 3 and Mg powders used as starting materials were blended in stoichiometric amounts and ...

Adhesive and Cohesive Strength in FeB/Fe2B Systems
Journal of Materials Engineering and Performance, 2018In this work, FeB/Fe2B systems were evaluated by the scratch test. The powder-pack boriding process was performed on the surface of AISI M2 steel. The mechanical parameters, such as yield stress and Young’s modulus of the boride layer, were obtained by the instrumented indentation technique. Residual stresses produced on the boride layer were estimated

Amorphization of Al50(Fe2B)30Nb20 Mixture by Mechanical Alloying
Metallurgical and Materials Transactions A, 2013An amorphous Al50(Fe2B)30Nb20 powder mixture was prepared by mechanical alloying in a high-energy planetary ball-mill under argon atmosphere. Morphologic, microstructural, and structural changes during the milling process were followed by scanning electron microscopy and X-ray diffraction.

Indentation size effect on the Fe2B/substrate interface
Surface and Coatings Technology, 2011Abstract This study evaluated the indentation size effect on the Fe 2 B/substrate interface using the Berkovich nanoindentation technique. First, the Fe 2 B layers were obtained at the surface of AISI 1018 borided steels by the powder-pack boriding method.

Hard iron boride (Fe2B) on 99.97wt% pure iron
Vacuum, 2006Abstract Some properties such as hardness and fracture toughness of boride formed on the 99.97 wt% pure iron were investigated. Boronizing was carried out in a solid medium, consisting of Ekabor powders of 5% B4C as donor, 5% KBF4 as an activator and 90% SiC as diluent at 800 °C for 2, 4 and 8 h.

Charge and spin density distributions in the ferromagnetic alloy Fe2B
Philosophical Magazine and Journal, 1971The charge and spin density distributions in the ferromagnetic intermetallic compound Fe2B have been determined from x-ray and neutron scattering measurements. The results demonstrate significant deviations from spherical symmetry in the electronic configurations of the iron atoms.

A Numerical–Experimental Study of Wear Resistance of FeB/Fe2B Systems
Journal of Materials Engineering and Performance, 2021In this study, the tribological performance of two FeB/Fe2B systems formed at the surface of an AISI 316L stainless steel was evaluated experimentally as well as numerically using the configuration rotatory pin-on-disk test, without lubricant and using a ball as a counterpart.
