The tantalum carbides, TaC x, have been repeatedly shown to harden dramatically with
some loss of carbon content, then soften with further decarburization. First observed in 1963 …

A dual phase boride and carbide ceramic with the nominal composition (Ti 0.2 Zr 0.2 Hf 0.2
Nb 0.2 Ta 0.2) B 2 and (Ti 0.2 Zr 0.2 Hf 0.2 Nb 0.2 Ta 0.2) C was prepared by reactive …

Abstract (Zr 0.196 Hf 0.02 V 0.196 Nb 0.196 Mo 0.196 W 0.196) C x complex concentrated
ceramics (CCC) with variable carbon non-stoichiometry are fabricated by hot-pressing …

We unveil the role of carbon vacancies and propose to tailor its concentration for enhancing
mechanical performance in high-entropy carbides (HECs). This is demonstrated by …

High-entropy alloys (HEAs) have gained increasing attention over the decades, owing to
their distinctive properties. Electrodeposition stands out as a cost-effective and convenient …

Shape memory ceramics (SMCs) are regarded as stimulus-responsive intelligent materials,
capable of a martensitic phase transformation under the stimuli of temperature and/or stress …

Mechanical properties of a range of high-entropy rocksalt carbides are investigated via ab-
initio modeling and experimental verification. It is found that elastic constants, hardness, and …

High entropy carbide ceramics have attracted much attention because of their high hardness
and chemical inertness, but the relatively low fracture toughness limits their actual industrial …

Despite the high hardness of high-entropy carbides, their applications are limited by their
low fracture toughness. This study reports the successful preparation of two high-entropy …

The fracture toughness (K IC) of high-entropy oxides (HEOs) is critically important for several
applications, but identification and quantification of the toughening mechanisms resulting …
