An improved reconstruction procedure for the correction of local magnification effects in 3D Atom Probe

A new 3DAP reconstruction procedure is proposed, which accounts for the evaporation field of a secondary phase. It applies the existing cluster se lection softwares 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.
