Compositional dependence of thermal, elastic, and mechanical properties in Cu-Zr-Ag bulk metallic glasses

Starting from the two binary bulk glass formers in the Cu-Zr system, we systematically investigated the compositional dependence of glass formation, thermal, elastic, and mechanical properties in the Cu-Zr-Ag ternary bulk glassy alloys. Both CU(50-x)-Zr50Agx and CU(64-x)Zr36Agx series show a good combination of high glass-forming ability and high Poisson's ratio. However, compressive plastic deformation was only observed in CU(50-x)Zr50Agx series and the possible underlying mechanism is discussed. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd.
