The plasticity and the dynamic fragility of bulk metallic glass of a Zr,62 Cu,18 Ni,10 Al,10 alloy are studied by threepoint beam bending methods. We find that the alloy behaves super plastic not only at room temperature, but also at high temperatures. More importantly, it is found that the superplasticity increases with increasing temperature. In addition, the dynamic fragility parameter m for the supercooled liquid of this alloy is measured to be 34.87 and the supercooled liquid of Zr62 Cu18 Ni,10 Al,10 alloy behaves as a strong liquid.
