Figure 2: The 3D distribution of Cr, V, Ta and W in the as-deposited HEA alloy revealed by APT is shown in (a) to (d), respectively. 2D compositional maps of Cr, V, Ta and W using a 25x1x20nm slice of APT data are shown in (e) to (h) where the color scale bars below each figure denotes concentration range for each element. The top down view of the APT result showing the location of three distinct grain boundaries captured by APT as well as corresponding elemental segregation is shown in (i-l).
