Oxidation of ZrB 2 ‐based ultrahigh‐temperature ceramic composites containing 10, 20, and 30 vol% SiC was performed at 1900°C for 1 h in air. –20 exhibited the highest oxidation resistance this temperature formed a dense coherent oxide scale after oxidation, whereas strong degradation observed both –10 –30 SiC. In addition, cracks spallation were also detected latter materials. The behaviors –SiC investigated. effect content analyzed models proposed to describe microstructures.
The electronic structures and optical properties of the monoclinic ZrO2 (m-ZrO2) are investigated by means first-principles local density approximation (LDA) + U approach. Without on-site Coulomb interactions, band gap m-ZrO2 is 3.60 eV, much lower than experimental value (5.8 eV). By introducing interactions 4d orbitals on Zr atom (Ud) 2p O (Up), we can reproduce gap. calculated dielectric function exhibits a small shoulder at edge in its imaginary part, while tetragonal cubic it absent,...
Understanding the deformation and strain at elevated temperature is a critical factor for stability of aerodynamic shape, an important consideration thermal protection system design. However, accurate measurement high temperatures challenge. Here, we present study full-field mapping up to 2000 °C using digital image correlation (DIC) method, which mainly depends on quality speckle patterns specimen surface. In our study, values are analyzed by DIC method while specimens heated large electric...
