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 …

Field‐assisted sintering technology/Spark plasma sintering is a low voltage, direct current
(DC) pulsed current activated, pressure‐assisted sintering, and synthesis technique, which …

Seven equimolar, five-component, metal diborides were fabricated via high-energy ball
milling and spark plasma sintering. Six of them, including (Hf0. 2Zr0. 2Ta0. 2Nb0. 2Ti0. 2) …

Ceramic materials having melting points higher than 3000° C and suitable for structural
applications at above 2000° C are commonly known as Ultra-High Temperature Ceramics …

Composites are, in general, a rapidly evolving and growing technical field with a very wide
range of applications across the aerospace, defence, energy, medical and transport sectors …

The MAB phases are atomically layered, ternary or quaternary transition metal (M) borides
(TMBs), with the general formula (MB) 2 z A x (MB2) y (z= 1–2; x= 1–2; y= 0–2), whose …

High-entropy materials often outperform their lower-entropy relatives in various aspects,
such as thermal stability and fracture toughness. While there are extensive research …

A series of dual-phase high-entropy ultra-high temperature ceramics (DPHE-UHTCs) are
fabricated starting from N binary borides and (5-N) binary carbides powders.>∼ 99 …

Ceramics are usually composed of randomly oriented grains and intergranular phases, so
their properties are the statistical average along each direction and show isotropy …

Refractory transition-metal diborides (TMB 2) are candidates for extreme environments due
to melting points above 3000° C, excellent hardness, good chemical stability, and thermal …
