The orthorhombic boride crystal family XYB14, where X and Y are metal atoms, plays a critical role in a unique class of superhard compounds, yet there have been no studies aimed at understanding the origin of the mechanical strength of this compound. We present here the results from a comprehensive investigation into the fracture strength of the archetypal AlLiB14 crystal. First principles, ab initio, methods are used to determine the ideal brittle cleavage strength for several high-symmetry…

Atomic bonding in the AlLiB 14
Abstract The underlying nature of atomic bonds in the orthorhombic AlLiB 14 crystal is studied using first-principles methods. Significant charge transfer is observed upon bonding, which is

TLDR
An ideal brittle cleavage model is used to study the impact of C doping on the mechanical properties of AlLiB14, and it is concluded that introducing C to the crystal decreases the ideal fracture strength by 3.3 GPa, which is about a 12% reduction in overall strength.
Lattice instability in the AlMgB14 structure
The lattice dynamics of the AlMgB14 structure is characterized by phonon vibrational modes that are calculated from first-principles methods. The stoichiometric composition of AlMgB14 is found to

TLDR
This work studies the adhesion and decohesion of Cu(1 0 0) surfaces using density functional theory (DFT) calculations and finds that the transition occurs via a localization of bond strain in the vicinity of the cleavage plane, which resembles the strain localization at the tip of a sharp crack that is predicted by linear elastic fracture mechanics.
First-principles study of crystalline and amorphous AlMgB14-based materials
We report first-principles investigations of crystalline and amorphous boron and M1xM2yXzB14−z (M1, M2 = Al, Mg, Li, Na, Y; X = Ti, C, Si) phases (so-called “BAM” materials). Phase stability is

TLDR
AlLiB14 is examined as a potential high-temperature thermoelectric material and it is found to have a band gap of 2.13 eV, and an electronic dispersion with characteristic indicative of having a high Seebeck coefficient.
