High-entropy ceramics with five or more cations have recently attracted significant attention
due to their superior properties for various structural and functional applications. Although …

Ultra-high temperature ceramics (UHTCs) are generally referred to the carbides, nitrides,
and borides of the transition metals, with the Group IVB compounds (Zr & Hf) and TaC as the …

Protonic ceramic fuel cells (PCFCs), capable of harmonious and efficient conversion of
chemical energy into electric power at reduced temperature enabled by fast proton …

The traditional way of densifying high-melting-point ceramics at high temperatures with long
soaking time leads to severe grain coarsening, which degrades the mechanical properties of …

Abstract (VNbTaMoW) C high entropy carbide was fabricated by reaction synthesis using the
constituent metal and graphite powders as raw materials. Phase formation and composition …

Some aspects of heat transfer upon the interaction between components with a sharp
leading edge and high-enthalpy high-speed flow of dissociated air have been considered; …

The grain growth kinetics and densification mechanism of (TiZrHfVNbTa) C high-entropy
carbide ceramic are investigated in this work. A single phase carbide with a rock-salt …

High-entropy carbide ceramics (Ti 0.2 Hf 0.2 Nb 0.2 Ta 0.2 W 0.2) C is prepared from five
transition metal oxides and graphite by reactive spark plasma sintering. X-ray diffraction …

High-temperature mechanical properties of medium-entropy carbide ceramics have
attracted significant attention. Tailoring the microstructure is an effective way to improve …

In this work, phase evolution, solid solution formation and diffusion behavior of three binary
systems, including TaC–HfC, TaC–ZrC and HfC–ZrC, were investigated. In this regard, pure …
