Abstract
A nanocrystalline Fe-5.1 at.%Al alloy is characterized by atom probe field ion microscopy. The measurements show that there is a significant inhomogen eity in the distribution of Al within grains, and an accumulation of oxides and nitrides and high concentrations of Al at the grain boundaries. It is suggested that these grain boundary impurities are responsible for the prev iously found good thermal stability of grain size in this alloy.
