$In~situ$ diffuse scattering of neutrons in alloys and application to phase diagram determination

The study of many phase diagrams relies on the phase stability of substitutional alloys. If the order can be described as an atomic distribution on an underlying lattice, and if the interactions can be expressed in terms of pairs and other multiplet potentials between the atomic species, the phase stability should be deducible from these potentials, along with other properties, such as antiphase boundaries, core structures of the dislocations in ordered compounds…
