| 英文摘要 | The influence of lattice misfit on the occupation behavior and the ductility effect of Zr in Ni-Ni_3Al alloys were explored. It is found in energy analysis that the preferable site of Zr between Ni sublattice and Al sublattice will change under different lattice misfit, however, the Zr prefers to segregate Ni phase rather than Ni_3Al phase in all lattice misfit range, which makes it impossible for Zr to go into Ni_3Al phase to occupy Al sublattice in Ni-Ni_3Al system. Bond order (BO) analysis shows that the localized ductility effect of Zr differs in different region, and the comparison between Zr-free and Zr-doped BO analysis successfully explain the mechanism of the embrittlement of Ni-Ni_3Al alloys and the ductility effect of Zr. |
