Abbreviated Series Title The mechanical properties of grain boundaries in aluminium alloys appear to be very strongly affected by subtle changes in the local chemistry. Due to these microstructural features being on the nanometre scale they are at the limit of conventional TEM based analysis techniques. X-ray and atom probe microanalysis techniques have been applied to the study of grain boundary chemistry in a commercial aluminium alloy. A variety of heat treatments resulting in different stress corrosion cracking susceptibilities have been invesigated. This paper compares typical analyses from one heat treatment to show that the combination of these two techniques with their quite different intrinsic advantages and limitations allows clearer characterisation of the variations in grain boundary chemistry.
