ABSTRACT
Energy dispersive systems used in transmission electron microscopy, give a correspondence between a part in the image plane and a part in the spectrum, perpendicular to the dispersion direction. Taking advantage of this property, with the new spectum 2D detection devices (CCD matrix), the spatial resolution of EELS analysis can approach the subnanometre scale. With this technique, ultramicrotomed sections of anodized Al-Cr 4% alloy samples have been studiedto determine the locations of alloying species and consequences of their anodic oxidation.
