Despite the recent progress in developing various microanalytical
tools of better spatial resolution and more sensitivity to chemical
analyses for the study of various defects in metallic solids the
Field-Ion Microscope (FIM) still remains the only instrument up to
now to resolve single atoms in the surface of a metal. Fifteen
years after Milller ) invented the FIM he was also the first to
combine the FIM with a time-of-flight (ToF) mass spectrometer - the
so-called Atom-Probe FlM - to identify the chemical nature of
single atoms imaged in the FIM2). Originally the motivation to
develop the ToF atom probe was to use this method to obtain some
more fundamental understanding of field ionization and field
evaporation, the most basic physical processes in field-ion
microscopy. Even after the successful combination of a FIM with a
ToF atom probe had been accomplished, the technique was rarely
applied to metallurgical investigations since for a fairly long
period only refractory metals such as tungsten, molybdenum,
iridium, etc. could be imaged in the FIM. How ever, these metals do
not playa very important role in metallurgy. Only when Turner et 3
al. ) substituted the conventional phosphorescent screen of the
field-ion microscope with micro-channel electron multiplier arrays,
termed micro channel plates, did it become possible to image in the
FIM the less refractory metals like Fe, Cu, Ni and even AI."
