| 中文摘要 | Solid state Nb-93 nuclear magnetic resonance spectroscopy has been employed to investigate the atomic and electronic structures in Ni-Nb based metallic glass (MG) model system. Nb-93 nuclear magnetic resonance (NMR) isotropic metallic shift of Ni60Nb35Sn5 has been found to be similar to 100 ppm lower than that of Ni60Nb35Zr5 MG, which is correlated with their intrinsic fracture toughness. The evolution of Nb-93 NMR isotropic metallic shifts upon alloying is clearly an electronic origin, as revealed by both local hyperfine fields analysis and first-principle computations. This preliminary result indicates that, in addition to geometrical considerations, atomic form factors should be taken into a description of atomic structures for better understanding the mechanical behaviors of MGs.
