The computational results exhibited that the solid solubility of nitrogen element in the cubic-B1 Ta(C,N) phase was up to 50 at.%. If nitrogen content was smaller than 30 at.%, Ta(C,N) showed Poisson's ratio lower than 0.26 and brittle fracture feature during tensile simulations. As for Ta(C,N) with nitrogen content in the range from 30 to 50 at.%, both Poisson's ratio larger than 0.26 and structure evolution during tensile signified their ductile characteristics, which monotonically rose with the increase of nitrogen content. The calculated maximum toughness of Ta(C<sub>50%</sub>N<sub>50%</sub>) was 384.3 GPa%, which was 92% larger than that of TaC. Structural analysis revealed that solid solution of nitrogen element enhanced distortion ability of bond length and angle, and transformed anisotropic distortion in TaC to the isotropic one in Ta(C,N), which led to phase transition from face-centered cubic to hexagonal close packed. It was found that the spatial distribution characteristics change of orbital hybridization from isotropy in TaC to anisotropy in Ta(C,N) was the underlying reason for phase transformation, which was even facilitated after loading tensile strain. This indicates that phase transition engineering motivated by orbital hybridization regulation is an effective routine to improve material toughness.</p>","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 9","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is long established that these properties can be enhanced by pinning phase addition. However, the innate fragility of top-seeded melt growth has prohibited a substantial amount of pinning from being added to bulks grown by top-seeded melt growth. Due to its robustness, the newly developed single-direction melt growth (SDMG) method should allow the integration of significantly higher mass concentrations into the superconducting matrix.

A standardized methodology to optimize pigment quality is developed, based on laser parameters such as pulse width, frequency, speed, power, and line spacing. Scanning electron microscopy (SEM) is used to determine the optimal laser conditions for obtaining a continuous, defect-free coating, showing that the embedded particles on the surface exhibit a nearly spherical morphology with diameters below 100 nm. The sample with the highest surface quality is further analyzed structurally and optically. X-ray diffraction (XRD) confirms the presence of a pure spinel phase without secondary phases, along with a vitreous phase due to pigment embedding. Fourier-transform infrared spectroscopy (FTIR) and Raman spectroscopy reveal the characteristic vibrational bands of a normal spinel structure.
