The Kinetics and Dry-Sliding Wear Properties of Boronized Gray Cast Iron
Advances in Materials Science and Engineering, 2013 Some properties of boride formed on gray cast iron (GCI) have been investigated. GCI was boronized by powder-pack method using Commercial LSB-II powders at 1123, 1173, and 1223 K for 2, 4, 6, and 8 h, respectively.

Alloying effect on boride formation behaviour in cast TiAl alloys
, 2017 Boron addition has been used to refine the microstructures in TiAl castings, such as LPT blades, to improve ductility. However, boride precipitates with undesired morphologies could reduce ductility and even wipe out the entire benefit from grain ...

Hydrogenation of Magnesium Nickel Boride for Reversible Hydrogen Storage
, 2015 We report that a ternary magnesium nickel boride (MgNi2.5B2) mixed with LiH and MgH2 can be hydrogenated reversibly forming LiBH4 and Mg2NiH4 at temperatures below 300 °C. The ternary boride was prepared by sintering a mechanically milled mixture of MgB2

Hard iron boride (Fe2B) on 99.97wt% pure iron
, 2006 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 ...

New transformation mechanism of TiB from Bf to B27 structure in β-solidified TiAl alloys
Materials Research LettersBoth 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).
