Orientated Imaging Microscopy

Extract

With the complexity of polycrystalline materials, a number of techniques have evolved to assist in the resolution of the crystallography of these materials. Conventional methods provide partial information regarding grain size, and can produce estimated orientation distributions. However, these techniques have not been able to provide the spatial placement of lattice orientations, which is necessary for a complete picture of the microstructure of a materials sample. Furthermore, many materials characteristics, such as fracture and corrosion, are determined by site-specific, rather than average, crystal lographic features.
