Preparation and properties of composite material based on hafnium diboride and aluminum [PDF]

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Hafnium diboride (HfB2) in aluminum matrix (Al) material was prepared by diffusion sintering of a mixture of hafnium diboride and aluminum micropowders. The effect of the hafnium diboride content (HfB2) in the aluminum matrix (Al) on sintering characteristics and properties of the samples is presented.

Ti₃C₂T_x MXene-Zirconium Diboride Based Ultra-High Temperature Ceramics. [PDF]

Adv Sci (Weinh)
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

Synthesis of Binary Transition Metal Nitrides, Carbides and Borides from the Elements in the Laser-Heated Diamond Anvil Cell and Their Structure-Property Relations. [PDF]

Materials (Basel), 2011
Transition metal nitrides, carbides and borides have a high potential for industrial applications as they not only have a high melting point but are generally harder and less compressible than the pure metals.

Interaction between Electron and Phonon Subsystems in Hafnium Diboride [PDF]

METALLOFIZIKA I NOVEISHIE TEKHNOLOGII, 2016
Ab initio calculation of the electron???phonon coupling functions is carried out, using full potential LMTO method. Low value of the averaged electron??? phonon interaction constant for HfB??? ??=0.17 indicates that there is no evidence of superconductivity in this compound.

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.
