Abstract The ablation behavior of (Hf–Ta–Zr–Nb–Ti)C high‐entropy carbide (HEC‐0) was investigated using a plasma flame in air for different times (60, 90, and 120 s) at about 2100°C. effect SiC content on the resistance HEC– x composites ( = 10 20 vol%) also studied. linear rate HEC‐0 decreases with increasing time, showing positive role oxide layer complex composition. HEC–10 vol% (0.3 µm s −1 ) is only 10th that HEC‐0, significant improvement resistance, probably due to formation...
In this paper, Si<sub>3</sub>N<sub>4</sub> was used as a novel solid-state sintering additive to prepare AlON transparent ceramics with high transparency and flexural strength via the pressureless pre-sintering hot isostatic pressing (HIP) method at relatively low HIP temperature (1800 ℃). The effect of content on phase, microstructure, optical property, investigated. experimental results showed that Si element homogenously distributed in both pre-sintered HIPed ceramics. densification...
Sintered ceramics of β‐ Sr 2 SiO 4 : Eu 2+ , R 3+ ( = Tm Gd ) were prepared and their spectroscopic properties evaluated. A large enhancement green photostimulated luminescence PSL was observed from codoping with at a recognizable intensity level, the most efficient obtained when concentration 0.002. It proved that introduction created number oxygen vacancies which serve as traps for electrons excited by UV irradiation. In addition, distinguishable difference between photoluminescence PL...
Abstract Rare-earth disilicates are promising candidates for thermal and environmental barrier coatings (TEBC) in gas turbines that safeguard SiC f /SiC ceramic matrix composites (CMCs) from degradation attacks. Here, we report a systematic investigation on novel TEBC material, γ-Y 1.5 Yb 0.5 Si 2 O 7 . The γ-phase quarter molar ytterbium–doped yttrium disilicate exhibited low conductivity (1.72 W·m −1 ·K at 1200 °C) reduced intrinsic expansion (3.17 ± 0.22 × 10 −6 K up to 1000 °C), ensuring...
Abstract A pressureless two‐step sintering method was used to densify high‐entropy carbide (Ti 0.2 Zr Hf Nb Ta )C, with high density and good mechanical performance. The material heated up 2200°C subsequently soaked at 1900°C for 2–8 h the incorporation of 2–4 wt.% phenolic resin. With increasing resin content, large‐sized pores disappeared, average grain size decreased. However, increased holding time from 2 8 h, pore did not change significantly, 96.2%, evident growth graphite observed....
