This workshop introduces atom probe tomography (APT), covering the fundamental principles of the method, data collection, reconstruction, and other analysis techniques, as well as specimen preparation methods. Attendees will also have the opportunity to participate in a live demonstration of the technique and learn how the Local Electrode Atom Probe operates.

The combination of high-resolution electron microscopy imaging and nanomechanical testing in situ provides detailed insights into deformation mechanisms and how they relate to the local materials structure.  In a nanoindentation mode with a pyramidal probe, or utilizing focused ion beam machining to do uniaxial compression, these methods can be highly localized to evaluate critical components of materials microstructures that are not typically accessible from larger scale methods.  Where compression testing offers detailed insight into stress-strain behavior and the accompanying deformation mechanisms, nanoindentation can map out hardness/modulus in a high-throughput manner that can be correlated with maps from other characterization methods.
