Sulfur-bound biomarkers of a Monterey shale and a Greenland lake sediment
, 2009 Seeking to reconstruct the biogeochemical processes that produced organic sulfur compounds in two unique depositional environments, we used the nickel boride desulfurization reaction to release hydrocarbons from sulfur-bound macromolecules not otherwise ...

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.

Effect of boriding time on the effective thermal diffusivity of the borided AISI 1018 steel
Scientific ReportsBoriding is a thermochemical process by which the surface of metallic materials is strongly improved for many applications. When boriding is applied to ferrous alloys, a boride layer containing mainly a single-phase Fe $$_{2}$$ B or a double-phase Fe $$_{

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 ...
