1 前言粘度是表征金属玻璃高温流变特性的一个重要的动态参量,并与金属玻璃的玻璃转变、结晶及扩散过程紧密相关。所以,测量金属玻璃的粘度对于进一步认识金属玻璃在高温下所表现出的粘弹性和粘范性行为以及金属玻璃的生成能力、玻璃转变及结晶过程、扩散过程等是非常重要的。通过粘滞性流变激活能的测量更可以进一步认识这些过 1 Introduction Viscosity is an important dynamic parameter to characterize the rheological properties of metallic glass at high temperature and is closely related to the glass transition, crystallization and diffusion process of metallic glass. Therefore, measuring the viscosity of metallic glass is very important for further understanding the viscoelasticity and viscosity behavior of metallic glass at high temperature, as well as the ability of metallic glass to be formed, glass transition and crystallization process, diffusion process and so on. These can be further appreciated through the measurement of rheological activation energy
