Abstract

Diffuse neutron scattering experiments have been performed on a single crystal Fe0.8Al0.2at T-1013K. The data are analysed in terms of short-range order and lattice displacements. Effective pair-interactions have been determined by the inverse Monte Carlo method.Further measurements of the temperature dependence of the diffuse scattering reveal a long-range ordered phase with the B32 structure below T∼ 650K. This new phase is related to the influence of the magnetism on the chemical ordering in the, iron-aluminum alloys.
