一种新概念的伪三元扩散偶用于多组分体系扩散系数的估算

A novel concept of pseudo ternary diffusion couple for the estimation of diffusion coefficients in multicomponent systems

Neelamegan Esakkiraja, Aloke Paul

摘要:

通过简化Onsager形式的数学复杂性,提出了一种多组分体系中的伪三元扩散偶技术,用于估算互扩散系数的组成依赖值。否则,在具有三个以上组件的系统中遵循传统方法是不可能的。其他替代方法估计随机选择的组成范围内的平均扩散系数,并且缺乏物理意义。这种方法可以在具有任意数量组分的多组分体系中遵循,条件是只有三个组分形成扩散分布,而其他组分保持恒定。

英文摘要:

A pseudo ternary diffusion couple technique in a multicomponent system by simplifying the mathematical complications of Onsager formalism is proposed for the estimation of composition dependent values of the interdiffusion coefficients. This is otherwise impossible following the conventional method in a system with more than three components. Other alternative methods estimate the average diffusion coefficients over a composition range of random choice and lack physical significance. This method can be followed in a multicomponent system with any number of components on the condition that only three components develop diffusion profiles keeping others as constant.
