Abstract

Crystallization processes of glass-glass interfaces in sputtered CuZr thin film nanoglasses were directly studied using in situ heating experiments in a transmission electron microscope (TEM). By combining the in situ technique with a sophisticated symmetry analysis based on nanobeam diffraction patterns (NBDP) and electron correlation microscopy (ECM) to capture the relaxation dynamics in the nanoglass, correlations between excess volume and nucleation kinetics are attained on a microscopic scale. Particularly, glass-glass interfaces with their increased excess volume promote the onset of crystal nucleation.

薄膜纳米玻璃弛豫动力学和晶体成核的原位透射电镜研究

采用透射电子显微镜(TEM)原位加热实验直接研究了溅射CuZr薄膜纳米玻璃中玻璃-玻璃界面的结晶过程。通过将原位技术与基于纳米束衍射模式(NBDP)和电子相关显微镜(ECM)的复杂对称分析相结合来捕捉纳米玻璃中的弛豫动力学，在微观尺度上获得了过量体积和成核动力学之间的相关性。特别是，玻璃-玻璃界面的过量体积的增加促进了晶体成核的开始。

期刊介绍： Materials Research Letters is a high impact, open access journal that focuses on the engineering and technology of materials, materials physics and chemistry, and novel and emergent materials. It supports the materials research community by publishing original and compelling research work. The journal provides fast communications on cutting-edge materials research findings, with a primary focus on advanced metallic materials and physical metallurgy. It also considers other materials such as intermetallics, ceramics, and nanocomposites. Materials Research Letters publishes papers with significant breakthroughs in materials science, including research on unprecedented mechanical and functional properties, mechanisms for processing and formation of novel microstructures (including nanostructures, heterostructures, and hierarchical structures), and the mechanisms, physics, and chemistry responsible for the observed mechanical and functional behaviors of advanced materials. The journal accepts original research articles, original letters, perspective pieces presenting provocative and visionary opinions and views, and brief overviews of critical issues.
