摘要

为了现场高精度测量熔体扩散，本文提出了一种多切片滑动射线摄影技术。该技术结合了多滑动单元技术和 X 射线射线摄影技术，并继承了两者的优点。它不仅能将扩散过程可视化，而且适用于低吸收对比度甚至无吸收对比度体系的扩散系数测量。此外，通过引入同位素，原则上可以同时高精度地测量自扩散和相互扩散。本文报告了与该技术的设计和实验有关的细节。在 Al80Cu20 熔体中进行的测量证明了该技术的可靠性和有效性。

A liquid metal diffusion measurement technique integrating the x-ray radiography and multi-slice sliding cell.

For measuring melt diffusion with in situ and high accuracy, this paper proposes a multi-slice sliding radiography technique. This technique combines the multi-sliding cell technique and x-ray radiography and inherits the advantages of both. It not only visualizes the diffusion process but is also suitable for the diffusion coefficient measurement of systems with low or even no absorption contrast. In addition, by introducing isotopes, self-diffusion and interdiffusion can, in principle, be measured simultaneously with high precision. The details related to the design of this technique and the experiments are reported in this paper. Reliability and validity of this technique are demonstrated by its measurements in Al80Cu20 melt.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
