Atom Probe Tomography (APT) Reference Datasets provided by NIMS

Microstructural analysis using the atom probe tomography (APT) can be broadly divided into three steps: (1) preparation of needle-shaped APT specimens, (2) APT measurement, and (3) APT data analysis. In recent years, dramatic advances in both the hardware and measurement programs of commercial APT instruments have led to the automation of "(2) APT measurement", making APT operation more accessible and user-friendly. On the other hand, "(1) preparation of needle-shaped APT specimens", which requires experience and skill, and "(3) APT data analysis", which demands a high level of specialized knowledge covering everything from APT fundamentals to materials science, remain as the main barriers to the effective utilization of APT. Therefore, to support "(3) APT data analysis", we plan to publish typical APT datasets for various materials as needed.
