Simulating the Solidification of Boride–Boride Eutectics
Powder Metallurgy and Metal Ceramics, 2017Computer simulations of structurization in boride–boride ceramics are performed using the standard version of phase-field theory. The simulations reproduce the main properties of eutectic structures observed in experiments, i.e., spatial segregation of components, structure formation from an overcooled melt, and complete decomposition of the system ...

Stability of Hyperlithiated Borides
The Journal of Physical Chemistry A, 1999Structures and energetics of BLin (n = 4−8) clusters are predicted using the SCF, MP2, and B3LYP methods with the 6-31G(d) basis set, including energy evaluations at G2MP2. Cohesive energies, defined as the enthalpies of the BLin → B + Lin reactions, and Li and Li2 elimination reaction enthalpies are also estimated at B3LYP.

Vacuum boriding of austenitic steel and the structure of the boride layer
Metal Science and Heat Treatment, 19751. Vacuum boriding of steel Kh18N10T in amorphous boron powder at 900–1000° leads to formation of a diffusion zone on the surface that consists of borides of the (Fe, Cr, Ni)2B and (Fe, Cr, Ni)B types, and austenite and ferrite. 2. With vacuum boriding of steel Kh18N10T at 900–1000° in powdered amorphous boron the boron diffuses ...

A comparison of borides formed on AISI 1040 and AISI P20 steels
Materials & Design, 2007 In this study, some properties of borides formed on the AISI 1040 and AISI P20 steel substrates were investigated. Boronizing was performed at 800, 875, and 950 degrees C for 2, 4, 6, and 8 h by using Ekabor 2 powders.

A kinetic model for the borided layers by the paste-boriding process
Applied Surface Science, 2004Abstract This work is dedicated to the study of the growth kinetics of the borided layers obtained by the paste-boriding process. A diffusion model based on Fick’s laws and coupled with a thermodynamic description of the Fe–B binary system was suggested to simulate the growth kinetics of the borided layers consisting only of Fe2B phase and ...
