Schematic structure of the cluster+glue-atom model in a body-center-cubic (BCC) lattice of an ABCD quaternary alloys. a 3D, (111)supercell and (100)supercell views of the CN14 cluster (the coordination number is 14) with its glue atoms (golden atoms at edge centers and blue atoms in the vertex positions). b Topological structure of each type of element in the BCC lattice generated by the CN14 cluster+glue-atom model. c Configurational transitions of the CN14 clusters via atomic rearrangements, including three ordered configurations (O1 and O2 with the #216 space group, and O3 with the #8 space group) and three random arrangements (R1, R2, and R3 with the #1 space group). The various colors characterize the different kinds of alloying elements for the given equiatomic ABCD BCC HEA alloys, which are kept consistently in the following related figures. In particular, the A, B, C, and D elements are in yellow, wine, green, and blue, respectively
