| 中文摘要 | A first-principles investigation on the synergetic effect of Re and P on Griffith rupture works of the gamma-Ni/gamma'-Ni3Al interface is performed. The calculated results indicate site preference of P at the gamma/gamma' interface is not changed by Re-addition but P-induced embitterment can be inhibited even reversed by the addition of Re at the adjacent atomic layer of P. The correlative effect between P and Re at the gamma/gamma' interface is also evaluated by a correlative energy function. It is found a strong repulsive interaction between P-doping and Re-addition is limited within a unit cell of gamma or gamma' phase and is not profitable for the strengthening of the gamma/gamma' interface. The electronic and geometric structures reveal a large interfacial separation and the depletion of electron densities in the interfacial region should be responsible for the potential inter-phase cleavage fracture site, and the deleterious effect of P can be attributed to a mutual influence of local elastic stain energy and atomic bonding energy in the doped system.
