为了更深入地了解非晶合金过冷液体的特性和晶化行为，本工作针对具有高断裂韧性和良好生物相容性并在柔顺机构和生物植入体方面具有应用前景的Zr₆₁Ti₂Cu₂₅Al₁₂非晶合金，采用快速扫描量热和常规热分析技术相结合，实现了6个数量级(10^-2~10⁴ K/s)升温速率的调控，揭示出超宽温度范围内过冷液体依赖于升温速率的动力学特性：过冷液体的动力学行为滞后于温度的快速变化，2者符合VFT方程；脆度系数的小幅变化(m = 35~47)意味着其过冷液体结构随温度变化比较平缓，从而表现出具有一定的“强”液体行为；通过平移时间维度坐标，得出从玻璃转变到熔点整个温度范围内的平均m ≈ 45。该非晶合金晶化过程中晶体生长的温度依赖性表明生长激活能随温度升高逐渐降低，单位温度下的激活能降约为0.5 kJ/(mol·K)，在玻璃转变温度附近，晶体生长动力学与黏性流动间发生解耦，通过引入解耦指数(ξ = 0.84)使得晶体生长动力学系数(U_kin)与黏度(η)在更宽的温度范围内符合幂律关系：U_kin ∝ η^-ξ。

Plastic deformation of amorphous alloys below the glass transition temperature is inhomogeneous and highly localized within narrow shear bands. However, the processing and manufacturing of amorphous alloys in their supercooled liquid state exhibit unique advantages for engineering application. Although the discovery of bulk metallic glasses has substantially expanded the processing time and temperature window, experimental research on the supercooled liquid states of amorphous alloys remains widely limited to narrow regions near either their glass transition temperature or melting point. The crystallization of supercooled liquids severely limits the characterization of their kinetic behavior in the high-temperature region. Therefore, an enhanced comprehensive understanding of supercooled liquid characteristics and crystallization kinetic behavior of metallic glasses is necessary. Zr₆₁Ti₂Cu₂₅Al₁₂ amorphous alloy shows broad application prospects in the fabrication of flexible mechanism components and biological implants because of its high fracture toughness, high elastic strain limit, and good biocompatibility properties. Six orders of magnitude (10^-2-10⁴ K/s) of heating rate changes were achieved for Zr₆₁Ti₂Cu₂₅Al₁₂ metallic glass by combining flash differential scanning calorimetry (FDSC) with conventional DSC. This implies that the kinetic characteristics of the alloy supercooled liquid is dependent on the heating rate of the alloy over an ultra-extensive temperature range. The kinetic behavior of the alloy supercooled liquid lags behind the rapid changes in temperature, and both follow the Vogel-Fulcher-Tammann equation. The small variation in the fragility index (m = 35-47) indicates that the supercooled liquid structure changes gently with temperature, thereby showing a “strong” liquid behavior. An average m ≈ 45 is obtained over the entire temperature range from the glass transition temperature to the melting point via time dimension coordinate translation. The dependence of crystal growth on temperature during the crystallization process of the Zr₆₁Ti₂Cu₂₅Al₁₂ amorphous alloy indicates that the activation energy of crystal growth gradually decreases with increasing temperature, and the reduction in activation energy per unit temperature obtained here is approximately 0.5 kJ/(mol·K). Near the glass transition temperature, decoupling occurs between crystal growth kinetics and viscous flow. The kinetics coefficient for crystal growth (U_kin) follows a power law relationship with viscosity (η) over a wide temperature range when an exponent ξ = 0.84 is introduced: U_kin ∝ η^-ξ.
