The development of space technology is proposing higher demands on the materials for uses in extreme environment. The present review is divided into five parts
with emphasis focusing on ultrahigh temperature carbides in recent years. Research progresses on mono-carbides
binary carbides
multicomponent high-entropy carbides and their composite materials
in respects of theoretical modeling and prediction
microstructure control and macroscopic proper ties improvement are reviewed. Hardness
toughness and high temperature oxidation resistance of these materials have been enhanced effectively. However
development of highly-efficient fabrication techniques for practical purposes
as well as further investigations on mechanisms of microstructure and properties are still required. Meanwhile
for novel high-entropy carbides
performance improvement by revealing the co-relations of composition and microstructure remains a top priority.
