Figure 4

A comparison of the size and density of dislocation loops in (A) non-annealed and (B) annealed nanocrystalline iron after ex situ irradiation to 4 × 1015 ions cm−2 using 400 keV Ar ions. Quantitative measurements of loop diameter are shown as a box and whisker plot (C) for the each of the grains indicated with black arrows in A and B.
