Abstract Scope |
Diffusion plays an essential role in material processes such as solidification, precipitation, casting, and creep. Diffusion couple is one of the traditional methods to study the diffusion behavior. The Boltzmann-Matano analysis was used to calculate interdiffusion coefficients based on diffusion profile data, which is usually determined by WDS/EPMA. In this study, a forward simulation analysis is used to analyze the error of interdiffusion coefficients based on a fast diffusion simulation program. The error of interdiffusion coefficients is found to be dependent upon both the diffusion behavior of a particular system and its magnitude. |
