Diffusion Equation and Its Solutions under Two Specified Conditions for α Component in a M-α-β Ternary System

The distribution of α component will change with the diffusion of β component in a M-α-β ternary system, as the result of the interactions between the two components. The diffusion equation of such process for α component has been set up, and the solutions under two specified conditions,the "ihitial stage" and "equilibrium stage", have been obtained.
