Exploring the three-dimensional nanoscale space around defects in Ni-based superalloys for aircraft applications employing atom-probe tomography

The research proposed is part of an extensive work aimed at investigating the formation of defects during the solidification of Nickel-based superalloys, where the goal is establishing criteria that enable avoiding their formation. We intend to employ the latest version of the Atom-Probe Tomograph, namely the Local-Electrode Atom-Probe (LEAP), which is the best analytical experimental tool available today for characterizing the chemistry of solid materials in the sub-nanometric scale.
