Fig. 5: Size distribution of A15 clusters and dislocation loops from Frenkel pair accumulation simulations.
From: Compact A15 Frank-Kasper nano-phases at the origin of dislocation loops in face-centred cubic metals
a The typically observed A15 clusters with sizes from 3 to 19 atoms. The size refers to the total number of atoms that contribute to the A15 cluster, as indicated at the bottom of Fig. 1. b Evolution of A15 cluster size as a function of dose in fcc Al and Cu. c The size of Frank \(\frac{1}{3}\langle 111\rangle\) loops in fcc Al and prismatic \(\frac{1}{2}\langle 110\rangle\) loops in fcc Cu. The reported sizes correspond to the loop circumference defined by DXA analysis70. For each dose, the colour code is applied such as the minimum and the maximum number of the loops always correspond to purple and yellow, respectively. The grey dotted lines indicate the limit of the regime where the loops are the only dislocation defects formed in Al and Cu, as defined in Fig. 4.
