Abstract

ABSTRACT Al–Cu melts were used to study interdiffusion under a transverse magnetic field (TMF) using X-ray imaging. A novel gravity-assisted automatic docking device was used to create a long capillary of the diffusion couple. Compared with the results acquired using energy-dispersive spectroscopy, X-ray imaging is more convenient and accurate to determine concentration profiles along long capillaries using the numerous gray value intensities in the imaging. Because a TMF can inhibit melt convection, the interdiffusion coefficient (D AlCu) was reduced after applying a TMF of 2 T. Our results demonstrate that the application of X-ray imaging is an efficient way to study ex-situ diffusion in liquid melts.

X射线成像在横向磁场作用下Al–Cu液态熔体扩散的原位研究

摘要:采用x射线成像技术研究了Al-Cu熔体在横向磁场(TMF)作用下的相互扩散。采用一种新型的重力辅助自动对接装置，形成了扩散偶的长毛细管。与能量色散光谱的结果相比，x射线成像利用成像中的众多灰度值强度来确定长毛细血管的浓度分布更加方便和准确。由于TMF可以抑制熔体对流，施加2 T的TMF后，相互扩散系数(dalcu)降低。我们的结果表明，应用x射线成像是研究液体熔体中非原位扩散的有效方法。

期刊介绍： Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate. Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
