| 英文摘要 | We report the combined experimental and theoretical investigations on high pressure structural stability of niobium carbide (NbC). The compressibility of NbC has been measured using angle-dispersive synchrotron X-ray diffraction in a diamond anvil cell (DAC) at room temperature and high pressure (up to 38.0 GPa), complemented with first-principles density-function theory calculations. The results imply that NbC shows bulk modulus of K-0 = 281 (6) GPa with a pressure derivative K'(0) = 6.2 (1.5) for its strong covalent bonding. In addition, indentation testing on the well-sintered bulk NbC obtained at 5.0 GPa/1400 degrees C yielded a Vickers hardness of 19.2 GPa and fracture toughness of 7.7 MPa m(1/2) at applied load of 10 kgf, demonstrating that binderless NbC prepared under high pressure should be a prospective hard material. |
