| Abstract | Traditional theories of interdiffusion in solids based on Fick’s first and second laws and Darken’s equations can not describe the relationship between the diffusion fluxes and the diffusion-induced stresses, because the subject matter of the traditional theories is the diffusing atom or atomic flux, not the volume unit within the interdiffusion field. For this reason, it is suggested that the concept of flow point in the interdiffusion field should be constructed to describe the diffusion-induced stresses and the phase growth. |
