Thermodynamic modeling of the borbarium ferroalloy smelting technological process

Metalurgija, 2020
A complete thermodynamic modeling of chemical transformations during carbothermic reduction of barium and boron from oxides has been performed. It was shown that during the processing of charge with a high BaO: BaO:B2O3(3:1), barium carbide (BaC2), iron ...

Physical properties of noncentrosymmetric superconductor Ru$_7$B$_3$

, 2008
Transition metal boride Ru$_7$B$_3$ was found to be a noncentrosymmetric superconductor with $T_{C}$ equal to 3.3 K. Superconducting and normal state properties of Ru$_7$B$_3$ were determined by a self-consistent analysis through resistivity($\rho_{xx ...

Influence of boriding treatment on the mechanical properties of Monel 400

Results in Surfaces and Interfaces
The Monel 400 nickel-copper alloy exhibits high corrosion resistance but low wear resistance. The boriding thermochemical treatment aims to improve wear resistance by increasing the surface of the material hardness. Previous studies on boriding Monel 400
