MS 3013-0

Brief

This course deals with diffusion and phase transformation in materials science. Subjects will be covered in the following. Diffusion includes Steady state, transient state, Fick's first and second laws, variable diffusivities, moving boundary, heterogeneous systems,atomic mechanism, Kirkendal effect and up-hill diffusion. Phase transformation includes nucleation, growth, and spinodal decomposition.
