The following articles involve the mainstream preparation process of high entropy ceramics, the influence of key process parameters on the microstructure and mechanical properties of high entropy ceramics, and improving the structural stability and performance of high entropy ceramics under ultra-high temperature, oxidation and erosion conditions.
Extreme high-temperature environments – typically above 1000°C (1832°F) and often exceeding 2000°C – are encountered in aerospace propulsion (rocket nozzles, jet engines), gas turbines, nuclear reactors, hypersonic vehicles, industrial furnaces, and protection systems for re-entry vehicles. Materials used in these conditions must resist creep, oxidation, thermal shock, and often corrosive combustion products while maintaining mechanical integrity.
