Electrical discharge machining of Al-TiB2 with a low-frequency vibrating tool

Science and Engineering of Composite Materials, 2014
Aluminum-based composite reinforced materials produced in situ with titanium boride (TiB2) particulates have higher potential for advanced structural applications where high specific strength modulus as well as superior temperature resistance is ...

Dual-phase ceramics based on multi-cation boride and carbide: Investigations at the nanoscale

Journal of Materiomics
A dual phase boride and carbide ceramic with the nominal composition (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)B2 and (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)C was prepared by reactive synthesis and consolidated by spark plasma sintering.

Self-affine patterns of boride layers

, 2007
In this study, the evaluation of interfaces on iron boride Fe2B growth obtained by paste boriding process was carried out. Fractal geometry is used like a powerful tool for the roughness analysis present during iron boride growth.

Hydrogenation of Magnesium Nickel Boride for Reversible Hydrogen Storage [PDF]

, 2010
We report that a ternary magnesium nickel boride (MgNi_(2.5)B_2) mixed with LiH and MgH_2 can be hydrogenated reversibly forming LiBH_4 and Mg_2NiH_4 at temperatures below 300 °C. The ternary boride was prepared by sintering a mechanically milled mixture

Effect of cooling methods on the tribological, oxidation and corrosion properties of CeO2 composite boronizing coatings on 4Cr5MoSiV1 steel

Journal of Materials Research and Technology
The cooling method has a very important effect on the microstructure and properties of the boride layer. In this study, a rare earth-Cr composite boronizing method to prepare boride ceramic coatings on 4Cr5MoSiV1 alloy steel was used.

Boride layer growth kinetics of the borided high alloyed steels

, 2015
In this study, the case properties and diffusion kinetics of high alloyed cold work tool steel borided in Ekabor-2 powder were investigated by conducting a series of experi-ments at temperatures of 1123, 1173 and 1223 K for 2, 4 and 6 h. The boride layer

Structural characterization of boride layer on boronized ductile irons

, 2004
In this work, some surface properties of ductile irons were improved by a thermo-chemical boronizing process. Boronizing was performed in a slurry salt bath consisting of borax, boric acid and ferro-silicon at 850 and 950 degreesC for 2-8 h.

ANALYSIS OF THERMODYNAMIC FUNCTIONS OF FERRUM BORIDES

Nauka ta progres transportu, 2010
The thermodynamic functions of iron boride and carbon-alloyed one Fe2(ВС) are considered. It is shown that iron boride Fe2B is quite thermodynamically stable within the temperature range from 1023 to 1223 K.
