Abstract
Inelastic nuclear resonant scattering spectra were measured on alloys of Fe3Al that were chemically disordered, partially ordered, and D0(3) ordered. The features in the phonon partial density of states of Fe-5 7 were found to change systematically with chemical short-range order in the alloy. Changes in the phonon partial density of states were mod eled successfully by assigning vibrational spectra to Fe-57 atoms in d ifferent first-nearest-neighbor chemical environments.
