Abstract
Energy-filtered transmission electron microscopy is used to image the nanoc omposite FeAl+Y2O3, an oxide-dispersion-strengthened intermetallic alloy, o ver a tilt range of +/- 60 degrees using inelastically scattered electrons only. The properties of electron spectroscopic imaging are exploited to rec over a projection relationship between the three-dimensional chemical conce ntration distribution and the micrographs. This allows recovery of the full information on volume shape, distribution, and homogeneity of the buried n anoparticles by backprojection. Restrictions to low atomic number, common i n bio-objects, are here overcome at the expense of higher electron exposure s. (C) 2001 American Institute of Physics.
