Ni self-diffusion in refractory Al-Ni melts

Stüber, Sebastian and Holland-Moritz, Dirk and Unruh, Tobias and Meyer, Andreas (2010) Ni self-diffusion in refractory Al-Ni melts. Physical Review B - Condensed Matter and Materials Physics, 81, 024204. American Physical Society. doi: 10.1103/PhysRevB.81.024204.

This work presents investigations on the Ni self-diffusion coefficient in Al-Ni melts forming the technological relevant intermetallic phases Al50Ni50 and Al25Ni75 by quasielastic neutron scattering. We found that the Ni self-diffusivity at constant temperature is nearly independent of the composition within the composition range between 0 and 50 at. % Al. This may be a result of the small composition dependence of the atomic volume observed in the same range of composition.
