This work describes crystallization mechanisms in a model ZrCu thin film metallic glass, synthesized through magnetron sputtering. Global-scale characterization techniques, including differential scanning calorimetry and X-ray diffraction, are compared with local-scale characterization obtained through transmission electron microscopy during isothermal heating. This multi-scale approach establishes the crystallization sequence of ZrCu thin film metallic glasses. Furthermore, it highlights the role of oxidation as a nucleation site, initiating the crystallization process. Once initiated, crystallization progresses as a propagating front, scanning and transforming the amorphous matrix. The combination of both global and local approaches yields consistent key thermodynamic values. Additionally, monitoring the advancing crystallization front during in situ high-temperature transmission electron microscopy provides access to crucial kinetic parameters, such as diffusion coefficients.

更好地了解 ZrCu TFMG 的结晶动力学：结合全局和局部原位方法的好处

这项工作描述了通过磁控溅射合成的 ZrCu 薄膜金属玻璃模型的结晶机制。将包括差示扫描量热法和 X 射线衍射在内的全局尺度表征技术与等温加热过程中通过透射电子显微镜获得的局部尺度表征进行比较。这种多尺度方法建立了 ZrCu 薄膜金属玻璃的结晶序列。此外，它强调了氧化作为成核位点的作用，引发结晶过程。一旦开始，结晶就会作为传播前沿进行，扫描并转变非晶基质。全局和局部方法的结合产生了一致的关键热力学值。此外，在原位高温透射电子显微镜中监测前进的结晶前沿可以获取关键的动力学参数，例如扩散系数。
