摘要:
非晶合金熔体的扩散是描述非晶合金熔体动力学行为的重要参数，不同于一般的金属熔体，非晶合金熔体的扩散行为往往具有自己独特的性质，如表现出典型的慢扩散行为和复杂的温度依赖关系等，但由于技术、理论上的原因，目前无论是国内还是国际上对扩散的研究都处于初步阶段。本文主要介绍了扩散系数的几种比较成熟的测量方法，其中包括最近本课题组在传统长管法和切单元法的基础上开发的滑动剪切技术，该技术能够有效消除加热阶段的扩散，是测量扩散系数的有效方法。同时，基于前人的测量结果和理论模型，本文对非晶合金熔体的扩散研究进行了系统的总结和讨论。
Abstract:
Abstract: Diffusion in amorphous alloy melts is an important kinetic parameter to describe the properties in melts. Different from the normal alloy melts, the diffusion behavior of amorphous alloy melts tend to have their own unique properties, such as presented a typical slow diffusivity and a complex temperature dependent. But the researches on atomic diffusion are still at a preliminary stage whether in domestic or international study due to technical and theoretical difficulties. This paper mainly introduced some measurement techniques of the diffusion coefficient, including our self-designed sliding cell method, which combined the merits of the traditional long capillary method and the shear cell method, and ruled out the undesired atomic diffuse occurs in heating process. It’s concerned as an effective way to measure the diffusion coefficients. In addition, based on the diffusion results and models of the amorphous alloy melts, the diffusion research in amorphous alloy melts were summarized and discussed.

Keywords: Amorphous alloy melts, Diffusion, Sliding cell method
