图9 基于温度-应力空间的宏观动力学相图，由黏度定义了金属玻璃的玻璃态和流变态[69]

Fig.9 Two-dimensional plot of viscosity as a function of temperature and stress in a model metallic glass (T0 = 860 K, σ0—the critical stress where η0 diverges in extrapolation to T = 0?K, σ—stress, η—viscosity, η0—the viscosity to define the glass transition)[69]
