摘要

几十年来，以一种或多种组分的末端浓度相似为特征的等浓度（IC）偶已被用于评估扩散和热力学相互作用。伪二进制（PB）偶是集成电路偶的一种极端情况。Sadhu等人最近提出了一种用于PB扩散偶联相互扩散分析的方程格式，在本工作中显示出在数学和物理上的缺陷。目前的工作在更广泛的多组分扩散框架中检查PB概念，以突出b[1]中提出的分析中的技术谬误和无效索赔。

Comments on “Practicing pseudo-binary diffusion couple method in ternary and multicomponent systems” published in Acta Materialia 294 (2025) 121127

Iso-concentration (IC) couples characterized by similar terminal concentrations of one or more components have been employed for many decades for assessment of diffusional and thermodynamic interactions. Pseudo-binary (PB) couple is an extreme case of IC couples. Sadhu et al [1] recently presented an equation scheme for the interdiffusion analysis of a PB diffusion couple, which is shown in the present work to be mathematically and physically flawed. The present work examines the PB concept in a broader framework of multicomponent diffusion to highlight the technical fallacies in the analysis presented by and the invalid claims made in [1].

期刊介绍： Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
