Fig. 7

a 3D APT reconstruction of two bubbles with a separation distance of 17.7 nm within a ROI of 5 nm diameter. The diameters of the two bubbles are 4.8 nm and 4.6 nm, respectively. b 2D simulated Ni concentration map; c Comparison of 1D Ni concentration line profiles obtained from APT along the line connecting the centers of the two bubbles with results from 2D IK model simulations. The grey regions represent the helium bubbles. Dashed lines indicate the bubble surface.
