Putative global minima have been located for clusters interacting with an aluminum glue potential for Nless than or equal to190. Virtually all the clusters have polytetrahedral structures, which for larger sizes involve an ordered array of disclinations that are similar to those in the Z, H, and sigma Frank-Kasper phases. Comparisons of sequences of larger clusters suggest that the majority of the global minima will adopt the bulk face-centered-cubic structure beyond Napproximate to500.
