Abstract
The decomposition of alloys can lead to concentration fluctuations wit h small amplitude and spatial extension. A technique of data evaluatio n, the repeated smoothing procedure (RSP), is described by which atom probe data of such alloys can be analysed. The procedure is applied to a Fe-Ni Invar alloy, annealed at 625 degrees C, and to two Cu-Ni allo ys, annealed at 300 degrees C and at 350 degrees C. Decomposition was observed and quantified in both alloy systems. (C) 1998 Elsevier Scien ce B.V. All rights reserved.
