Abstract

Diffusion in a regular solid solution was investigated. A thin plate of isotropic solid of constant surface molal fraction was considered. The regular solution is described by the parameter α. When α is positive, the attraction between unlike atoms is greater than the attraction between like atoms, and conversely. The depths of penetration and average molal fraction for a given period increase with increasing α. The separation of two curves for given α increase with increasing surface molal fraction. The diffusion coefficient is positive only if α is greater than −1/X(1 - X
