| 中文摘要 | Transmission electron microscopy characterizations and elastic properties of two quaternary carbides, i.e. Zr(2()Al(Si))(4) C(5) and Zr(3)(Al(Si))(4)C(6) are reported. The space group and atomic-scale microstructures of both compounds were determined using a combination of selected area electron diffraction, convergent beam electron diffraction, high-resolution transmission electron microscopy and Z-contrast scanning transmission electron microscopy. In addition, the combined experimental and theoretical studies on elastic properties for Zr(2)(Al(Si))(4)C(5) are presented. A full set of second-order elastic constants, bulk modulus, shear modulus, and Young's modulus were calculated using first-principles calculations. Both experimental and theoretical works demonstrated that quaternary Zr-Al-Si-C ceramics possess close elastic properties to ZrC. Furthermore, Zr(2)(Al(Si))(4)C(5) retained a high Young's modulus up to about 1580 degrees C, which can be attributed to its comparable activation energy of lattice drag process to that of ZrC.
