Order and Phase Separation in Alloys

Abstract

In an initially homogeneous alloy quenched from high temperature, local ordering and/or phase separation may occur on the way towards thermodynamic equilibrium at a lower temperature. Some of the related diffuse scattering effects, including those around the primary beam (small-angle scattering), are presented, and some recent results of X-ray and neutron scattering studies of short-range order and decomposition in some alloys are discussed.
