The appreciable progress has been achieved currently in the development of design
principles, synthesis, investigations and predictions of various groups of ultra …

A multitude of observed boron-based materials have outstanding superconducting,
mechanical, and refractory properties. Yet, the structure, the composition, and the very …

A recent study has demonstrated that MoB 2, transforming to the same structure as MgB 2 (P
6/mmm), superconducts at temperatures above 30 K near 100 GPa [C. Pei et al., Natl. Sci …

In this study, we have used density functional theory (DFT) calculations to characterize if and
how defects influence the stability and electronic/mechanical properties of MB 2 (AlB 2-type) …

We have deposited weakly textured substoichiometric NbB 2− x thin films by magnetron
sputtering from an NbB 2 target. The films exhibit superhardness (42±4 GPa), previously …

Although niobium borides have been extensively studied on their mechanical properties, a
systematic investigation on their potential metastable phases, superconducting excitations …

In Part 1 of this study, we investigated the macrokinetic parameters and phase formation
mechanism in the combustion front of Zr–Nb–B mixtures. In the second part, we produced …

Transition metal diborides in hexagonal AlB 2 type structure typically form stable MB 2
phases for group IV elements (M= Ti, Zr, Hf). For group V (M= V, Nb, Ta) and group VI (M …

It has long been known that foundry Al-Si alloys cannot reliably and consistently be grain
refined by means of Ti-containing master alloys due to reaction between Ti and Si. Over the …

Aiming to obtain a reliable description of the quaternary Al–B–Nb–Ti system, the
thermodynamic descriptions of the constituent binary systems B–Nb and B–Ti are revised by …
