During an examination of the Mo ss (Mo solid solution) + Mo 5 SiB 2 + Mo 2 B three phase alloys a lattice constant expansion was observed for the Mo ss . To identify the origin of the expansion, high precision analysis of scanning transmission electron microscopy images was carried out to determine the solid solution type of B atoms. A quantitative analysis of the non-rigid registration image demonstrates that the B is located at the octahedral sites of the Mo lattice. This conclusion is consistent with the expansion of lattice constant and the small solid solubility limit of B in Mo ss .
