摘      要：Nanostructured metals possess various excellent properties and offer the potential for a wide range of *** in the properties and performance of nanostructured metal components motivate a complete characterization of the microstructures and crystallographic orientations of nanostructured metals with nanoscale spatial *** well developed orientation mapping techniques for such characterization are electron backscatter diffraction(EBSD)in the scanning electron microscope and precession electron diffraction(PED)using diffraction spots in the transmission electron ***,these methods can only characterize the structure in two *** is still a great challenge to characterize grains in three dimensions,*** the interior of the nanostructured ***,three-dimensional orientation mapping in the transmission electron microscope(3 D-OMi TEM)was developed and further improvements of this technique are introduced in this *** of these orientation mapping techniques for structural and orientational characterizations are demonstrated by examples of surface-deformed metals with gradient nanostructures,and a sputtered gold film of nano-islands containing *** merits and challenges of each of these techniques are discussed and suggestions for further developments are proposed.
