The influence of cooling rate and alloy composition on the formation of borides during solidification of boron-containing TiAl alloys

, 2012
It has been found that for Ti-45Al-2Nb-2Mn-1B the long curvy borides were either TiB borides with Bf structure or Ti3B4 borides, and the blocky borides were either TiB borides with B27 structure or TiB2 borides.

Zirconium‐Based High Emissivity Multilayer Coating for Carbon/Carbon Composite With Enhanced Ablation Resistance

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
ABSTRACT A multilayer coating system was developed as an ablation and thermal protection measure for C/C composites. The multilayer coating architecture consists of SiC, ZrB2‐SiC (ZBS), and ZrC‐ZrO2 (ZZC) sublayers with a Sm2O3‐ZrO2 (SZC) topcoat.

A Hydride Route to Ternary Alkali Metal Borides: A Case Study of Lithium Nickel Borides

, 2019
Ternary lithium nickel borides LiNi3B1.8 and Li2.8Ni16B8 have been synthesized by using reactive LiH as a precursor. This synthetic route allows for the better mixing of the precursor powders, thus facilitating fast preparation of the alkali metal ...

The Microstructural Evolution and Mechanical Properties of Boron-Doped Ti₃₅Zr₃₀V₁₀Nb₂₅ Refractory High-Entropy Alloy

Crystals
The addition of oxygen or nitrogen in refractory high-entropy alloys (HEAs) has been widely reported, but studies on boron-doped HEAs have mainly focused on the segregation of boron elements at grain boundaries.

Tungsten Borides for Hydrogen Evolution Reaction and Oxygen Evolution Reaction in Alkaline Media

, 2021
Tungsten borides for water splitting performances can be optimized through the ball-milling and hot-pressing technique. Previous techniques for the synthesis of tungsten borides were a combination of electrochemical techniques, where the overpotentials ...
