Simulating the Solidification of Boride–Boride Eutectics

Powder Metallurgy and Metal Ceramics, 2017
Computer 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, 1999
Structures 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, 1975
1. 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 ...
