Contribution

It presents a novel iterative reconstruction procedure that integrates cluster identification and lateral homogenization, adaptable to existing software for better 3DAP reconstructions.

Findings

Successful application on simulated data

Effective correction of local magnification effects

Compatible with current reconstruction software

Abstract

A new 3DAP reconstruction procedure is proposed that accounts for the evaporation field of a secondary phase. It applies the existing cluster selection software to identify the atoms of the second phase and, subsequently, an iterative algorithm to homogenise the volume laterally. This Procedure, easily implementable on existing reconstruction software, has been applied successfully on simulated and real 3DAP analyses.
