“…The impact of this artifact on APT microanalysis of grain boundaries, heterophase interfaces, and other structural features has not been adequately addressed. Examples where this artifact may impact the data can be found throughout the literature (Seidman et al, 1994; Blavette et al, 1996; Larson et al, 2004; Thuillier et al, 2006; Tamion et al, 2007; Pereloma et al, 2008; Sha et al, 2009; Lozano-Perez et al, 2010; Ngamo et al, 2010; Weidow & Andren, 2010). In the present article, we investigate the impact of solute retention on the in-depth spatial performance of atom probe microanalysis of grain boundaries within different engineering materials and propose a methodology to correct for this significant artifact.…”
