摘要：

To date mosaic crystals are mainly in use as neutron monochromators. They are made by plastic deformation of high-quality single crystals. Although this procedure has been applied successfully in numerous cases, it may nevertheless result in an inhomogeneous or coarse microstructure, and the crystals may not show the expected performance. Recent efforts have concentrated on the creation of structural defects which are defined on a microscopic scale. Various successful approaches e.g. by plastic deformation with locally applied forces, by either static or dynamic elastic bending, or by making alloys of appropriate compositions and thermal treatments are discussed.
