Microstructure, mechanical, and thermal properties of compositionally complex (Hf,Zr,Nb,Ti)B2‒LaB6 ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.

The propagation characteristics of low frequency radio waves in magnetized hypersonic plasma sheaths

AIP Advances, 2023
Communication blackouts have been a main threat to hypersonic vehicles for decades. The low frequency communication was considered a potential approach to mitigate the “blackout.” Nowadays, low frequency transmitters serving underwater communication have

Bayesian probabilistic machine learning analysis of ceramic‐coated ultra‐high‐temperature carbon/carbon composites

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Regulatory agencies and key stakeholders are increasingly promoting the use of probabilistic approaches in design processes for large corporations. This shift is particularly emphasized in analyzing mechanical properties, such as fatigue and failure prediction.

Optimal speed of hypersonic cruise flight

Theoretical and Applied Mechanics Letters, 2011
AbstractA coupling frame of speed gain and maintain was suggested to assess the flight performance of hypersonic cruise vehicles (HCV). The optimal cruise speed was obtained by analyzing the flight performance measured by the ratio of initial boost mass to generalized payload.

Flight Control of a Novel Distributed Tiltrotor UAV With Experiments

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
Considering the mode transition control of a novel distributed tiltrotor UAV, we designed a fast fixed‐time sliding mode attitude controller to improve the response speed and robustness of the control system. Furthermore, a smooth mode transition strategy is developed to guarantee the stable conversion between fixed‐wing and helicopter modes ...

Designing phase‐adaptive UHTC multilayer composites: Layer width effects on mechanical and kinetic properties

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The B1 rocksalt transition metal carbides and nitrides are among the materials with the highest melting temperatures. Additionally, members of this group of materials possess high‐temperature strength with ductility facilitated by diffusional creep.

Pressure‐induced phase changes in polycrystalline Y2O3: Influence on structure and properties

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The micro‐ and nano‐structural effects of varying pressure and holding time at 1000°C during the high‐pressure processing of high‐purity, fine‐grained polycrystalline cubic yttrium oxide (c‐Y2O3) are investigated. The critical pressure required to induce the phase transformation from c‐Y2O3 to monoclinic‐Y2O3 (m‐Y2O3) ranges from 2.5 to 3.0 ...

A unified thermo‐chemo‐mechanical model for passive, active, and interfacial oxidation of silicon carbide

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Silicon carbide (SiC) is a promising material for hypersonic thermal protection systems, but its complex oxidation behavior—marked by transitions between passive, active, and interfacial bubbling regimes—can lead to catastrophic failure. Existing SiC models typically focus exclusively on either passive or active oxidation.
