| 英文摘要 | The first-principles methods have been employed to calculate the structural, electronic, and mechanical properties of the alpha, beta, and gamma phases of uranium under pressure up to 100 GPa. The electronic structure has been viewed in forms of density of states and band structure. The mechanical stability of metal U in the alpha, beta, and gamma phases have been examined. The independent elastic constants, polycrystalline elastic moduli, as well as Poisson's ratio have been obtained. Upon compression, the elastic constants, elastic moduli, elastic wave velocities, and Debye temperature of alpha phase are enhanced pronouncedly. The value of B/G illustrates that alpha and gamma phases are brittle in ground state. |
