研究了 Zr41Ti14Cu12.5Ni10Be22.5 大块金属玻璃 (MG) 的微观结构以及分解和结晶。确定分解对随后结晶的影响。通过成像板电子衍射强度测量，对MG进行了约化密度函数分析，并对MG中的分解和结晶进行了分析，以确定局部原子结构及其在分解和结晶过程中的发展。获得的 MG 的微观结构特征表明了块状 MG 与传统 MG 之间的差异。基于获得的MG局部原子结构信息，讨论了合金大玻璃形成能力的起源以及相分离对结晶的影响。
The microstructure as well as the decomposition and crystallization of the Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass (MG) has been investigated. The effects of the decomposition on the subsequent crystallization are determined. Reduced density function analyses for the MG, and the decomposition and crystallization in the MG have been made by means of electron-diffraction intensity measurement with imaging plate to deter mine the local atomic structure and its development in the course of the decomposition and crystallization. The microstructural characteristics of the MG are obtained demonstrating the difference between the bulk MG and conventional MG. The origin of the large glass forming ability of the alloy and the effect of the phase separation on the crystallization are discussed based on the obtained local atomic structural information of the MG.
