An atom probe field ion microscopy survey of several bulk metallic glasses including the zirconium-based glasses Zr55Al10Ni5Cu30, Zr46.25Ti8.75Cu7.5Ni10Be27.5, Zr41.2Ti13.8Cu12.5Ni10Be22.5, Zr57Nb5Al10Cu15.4Ni12.6, and Zr52.5Ti5Al10Cu17.5Ni14.6, together with two non-zirconium-based glasses Ti34Zr11Cu47Ni8, and Mg65Cu25Y10 is presented. Non random distribution of solute was observed in all these glasses and crystalline regions were observed in the Ti34Zr11Cu47Ni8 and Zr55Al10Ni5Cu30 materials.
