Microstructural and tribological characterization of niobium boride coating produced on AISI 1020 steel via multicomponent boriding

Materials Research Express, 2020
Niobium boride coating was produced on AISI 1020 steel by multicomponent boriding process. Boriding treatment at1000 °C for 4 h was followed by thermo-reactive diffusion technique at 1000 °C for 6 h under argon atmosphere.

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

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.

New transformation mechanism of TiB from Bf to B27 structure in β-solidified TiAl alloys

Materials Research Letters
Both transformations of structure and morphology occur on the borides formed in β-solidified TiAl alloys during heat treatment at 1300℃. Flake-like TiB(Bf) transforms to blocky TiB(B27).
