由于金属玻璃具有很宽的超冷液相区以及粘滞流体的流动特性,因此金属玻璃的超塑性引起了研究者越来越广泛的关注。金属玻璃塑性流动即均匀变形特性,可以分成牛顿流动和非牛顿流动,这两种流动都与温度和应变率有很大关系。尽管很多研究结果对了解金属玻璃带的超塑性非常有用,但是大多数的工作都是在简单的单轴拉伸实验条件下获得的,这种实验条件下的应变状态对工业成形过程来说并不真实。因 The superplasticity of metallic glass attracts more and more researchers’ attention due to its very wide supercooled liquid region and the flow characteristics of viscous fluid. Metal glass plastic flow that even the deformation characteristics, can be divided into Newtonian and non-Newtonian flow, both with temperature and strain rate has a great relationship. Although many studies have found it very useful to understand the superplasticity of metallic glass ribbons, most of the work is done under simple uniaxial tensile experimental conditions where the strain state is critical to the industrial forming process Not true. because
