Electrochemical metrics for corrosion resistant alloys.

Corrosion is an electrochemical phenomenon. It can occur via different modes of attack, each having its own mechanisms, and therefore there are multiple metrics for evaluating corrosion resistance. In corrosion resistant alloys (CRAs), the rate of localized corrosion can exceed that of uniform corrosion by orders of magnitude.

Towards an accurate volume reconstruction in atom probe tomography.

An alternative concept for the reconstruction of atom probe data is outlined. It is based on the calculation of realistic trajectories of the evaporated ions in a recursive refinement process. To this end, the electrostatic problem is solved on a Delaunay tessellation.

Applications of a versatile modelling approach to 3D atom probe simulations.

The article addresses application examples of a flexible simulation approach, which is based on an irregular mesh of Voronoi cells. The detailed atomic structure of APT field emitters is represented by Wigner-Seitz cells. In this way, arbitrary crystal structures can be modelled.

Modeling Atom Probe Tomography: A review.

Improving both the precision and the accuracy of Atom Probe Tomography reconstruction requires a correct understanding of the imaging process. In this aim, numerical modeling approaches have been developed for 15 years. The injected ingredients of these modeling tools are related to the basic physic of the field evaporation mechanism.

A full-scale simulation approach for atom probe tomography.

A versatile approach for simulation of APT measurements is presented. The model is founded on a Voronoi cell partition of 3D space. The partition is used in dual role: First, the atomic structure of the field emitter is depicted in a one to one relationship by single Wigner-Seitz cells.
