Synthesis of Dual Phase High Entropy Ultra‐High Temperature Ceramics From Different Carbon Sources
International Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.ABSTRACT Dual phase (Hf,Nb,Ta,Ti,Zr)C‐(Hf,Nb,Ta,Ti,Zr)B2 ceramics were synthesized by boro‐carbothermal reduction of oxides with different carbon black powders. The starting materials reacted differently based on the particle size, surface area, and additives in the carbon powder.

Analysis of Aerothermal Environment Characteristics of Hypersonic Rudder Shaft Gaps
气体物理Rudder shaft gaps of hypersonic vehicles affect the flow structure and corresponding aerodynamic heating characteristics, resulting in local peak heating near the rudder shaft, which poses a safety risk to the local thermal protection system.
