摘要 The plasticity and the dynamic fragility of bulk metallic glass of a Zr62 Cu18 Ni10 Al10 alloy are studied by three-point 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 Ni10 Al10 alloy behaves as a strong liquid.
