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.
