Ni diffusion in the high-temperature intermetallics Ni3Sb studied by quasielastic neutron scattering
Year: 1994
Type: article
Abstract: Nickel diffusion in the high-temperature phase of the intermetallic alloy Ni 3 Sb is extremely fast compared to diffusion in other intermetallics. We have studied quasielastic neutron scattering, which permits us to determine the elementary diffusion mechanism on an atomic scale. A model explaining diffusion by Ni jumps between the alpha - and gamma -Ni sublattices of the D0 3 (Fe 3 Si) structure has been tested and satisfactory agreement has been obtained.
