Abstract

The general aspects of cooperative disorder and related diffuse scattering from crystals are discussed and a general solution of a disorder problem is outlined. Diffuse scattering is due to deviations in space/or time from an average structure of strict long-range order, where long-range order refers to three-dimensional translational periodicity. Cobalt, Co-based alloys and sphalerite serve as examples of crystals with one-dimensional stacking disorder. The martensitic proto- ->> clino/ortho-enstatite transformation is governed by growth of embryonic preformed CE/OE faults within the PE matrix; the transformation mechanism can be understood from the disorder of the CE/OE product base. Complicated disorder phenomena in K-hollandites are related to different dimensionalities of the substructures. ZrO (sub 2) doped with various metal oxides shows defect structures which decisively determine material properties. The defect structure can be interpreted by a quantitative analysis of diffuse data in the frame of a model of correlated microdomains.
