Abstract

Recent technological advances in the design and fabrication of atom-probe tomographs and their commercialization are revolutionizing our ability to determine, on a sub-nanometer scale (atomic scale), the chemical identities of atoms in a nanostructure and to reconstruct this information in three dimensions. Thus, it is now possible to obtain data sets containing several hundred million atoms in a few hours, using either electrical or laser(femtosecond or picosecond) pulsing, and to reconstruct crystalline lattices using sophisticated software programs. Detailed quantitative results of the application of atom-probe tomography to study the kinetic pathways for precipitation in model nickel-based superalloys, Ni-Al-Cr and Ni-Al-Cr-Re, are presented as illustrative examples.
