“…For grain boundaries with lower concentrations, the Cr forms elongated regions of higher concentration, reaching 3 to 5 at%. These may correspond to Cr segregated to the dislocations that form a lowangle boundary, as already observed by APT [32,33], as indicated by the continuity of zone lines in the field desorption image.…”

“…In figure 2a, there is a line with high concentration of Cu element. Orientation analysis using the method proposed by reference [25] showed that the line corresponds to a high angle lamellar boundary. The details of Cu distribution within the marked column in (a) is shown in figure 2b.…”

Abstract. In this study, the distribution of Cu element in a Al (99.9996% purity)-0.3%Cu alloy cold rolled to 98% has been characterized in detail by using three-dimensional atom probe (3DAP) and ChemiSTEM techniques. The cold rolled structure is a typical high strain lamellar structure with an average boundary spacing of 200 nm, indicating a strong role of the small amount of Cu element in stabilizing the microstructure to form the fine scale structure. A heavy segregation of Cu element in the lamellar boundaries of high angles has been observed and the Cu concentration in the boundaries can be as high as 20 times of the nominal concentration of the alloy, which is considered as the main reason for a formation of a stable nanoscale lamellar structure.

“…The interfacial excess of phosphorus was then estimated by the ladder diagram [29], which has the advantage of being quite insensitive to a constant background or errors in the positioning of the atoms [30]. This diagram displays the variation between the accumulated solute atoms along the 1D volume as related to the total accumulation of all the atoms, as shown in Fig.…”

“…The P content at boundaries is generally more than 20 times higher than that in the neighboring bulk for all HAZ microstructures before step cooling, and is approximately 100 times higher after step-cooling in ICCGHAZ and CGHAZ. It has been reported that the structural change induced by P segregation reduces the bonding character of the host atoms [36], and the polar-covalent P-Fe interaction is weaker in the grain boundary environment [29,37], suggesting that the CGHAZ and ICCGHAZ are more susceptible to intergranular failure than BM and FGHAZ. On the other hand, the bulk P content decreased slightly after SC, probably due to the segregation of P to the nearby boundaries.…”
