Figure 5

For the CPFE data: (a) Slices 1–3 drawn on the block represent the three sections along the X-axis (slice 2 being at the indent centre) on which the residual deviatoric elastic strains predicted by CPFE are shown in (c) unimplanted sample and in (d) helium-implanted sample. For the Laue data (Laue measurements in¹⁴): (b) Visualisation of the measured sample volume. Superimposed are the X, Y, and Z axes, as well as the slices on which the measured deviatoric elastic lattice strains in (c) the unimplanted sample and (d) the helium-implanted sample are plotted. With respect to the initial crystallographic coordinates, X is [1 −1 0] direction, Y is [1 1 0] and Z is [001]. Slices 1–3 in experiments and simulations are at the same spatial positions and data in (c) and (d) is displayed on the same length- and colour-scales. The dotted white lines through (a) and (b) represent the depth at which the line plots in Figure C.1 in the Supplementary Material were extracted.
