(Zr35Ti30Be27.5Cu7.5)(100-x)Nb-x (x = 0, 5, 8, 10, 12, 15 at.%) glass-forming alloys were prepared by copper-mould suction casting. The alloys with different Nb contents exhibited different microstructures and mechanical properties. The proper addition of Nb (x = 5,8 at.%) to the Zr-Ti-Be-Cu system could ensure the formation of mostly amorphous phase. And excessive amount of Nb favored the formation of the bcc beta-Zr solid solution. The alloys with Nb contents of 8 at.%, 10 at.%, and 12 at.% displayed the distinguished plasticity of 11.1%, 7.6%, and 11.0%, respectively. Crown Copyright (C) 2010 Published by Elsevier Ltd.
