摘要

本文采用扩散偶实验和计算相结合的方法,研究了fcc Ag-Cu-Mg相在1073 K时的相互扩散系数和原子迁移率。根据实验组成曲线,采用Matano-Kirkaldy方法计算扩散路径交点处的扩散系数。利用已有的热力学描述,利用CALTPP(计算热物理性质)程序中的数值反演方法自动优化了fcc Ag-Cu-Mg相的原子迁移率。此外,通过模型模拟的组成曲线与测量值之间的良好一致性,验证了得到的原子迁移率是可靠的。此外,还给出了相互扩散系数、活化能和频率因子的三维曲面。目前得到的原子迁移率可用于银基合金的扩散数据库,为合金的微观结构模拟和材料设计提供依据。

Interdiffusion coefficient and atomic mobility for fcc Ag-Cu-Mg phase at 1073 K
In this work, the interdiffusion coefficient and atomic mobility for fcc Ag-Cu-Mg phase at 1073 K have been investigated by combining diffusion couple experiments and calculations. Based on the experimental composition profiles, the diffusion coefficients at intersection points in diffusion paths were calculated by means of Matano-Kirkaldy method. Using the thermodynamic descriptions available in literature, the atomic mobilities for fcc Ag-Cu-Mg phase were automatically optimized by numerical inverse method incorporated in the CALTPP (CALculation of ThermoPhysical Properties) program. Moreover, the obtained atomic mobilities were verified to be reliable through good agreements between the model-simulated composition profiles and the measured ones. In addition, three-dimensional surfaces for the interdiffusion coefficient, activation energy, and frequency factor were presented. The presently obtained atomic mobilities can be incorporated into the diffusion database for Ag-based alloys, which can contribute to microstructure simulation and materials design.

期刊介绍: University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded. Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
