Abstract
Abstract The properties of polycrystalline materials are usually described in terms of constitutive laws which relate a microscopic property to an average property of a grain boundary and a length scale such as the average grain diameter. It is known however that the properties of individual grain boundaries vary widely. The boundary to boundary differentiation in properties can be incorporated into models and related to experimental data if the individual grain orientations are determined and the rule connecting misorientation to properties is known. Excess volume at grain boundaries can be related to energy and diffusivity. It may be possible to measure excess volume experimentally using phase contrast imaging in the electron microscope and thus determine a quantity which is directly related to the properties of an individual boundary. In turn this information can in principle be exploited to relate the orientation distribution to property distribution and the behavior of a polycrystalline body.
