Diffusion of hydrogen in metals at arbitrary concentration gradients
A nonlinear equation of hydrogen diffusion in metals for general case of all concentration gradients is derived. The solution of linearized equation is presented. It is shown that it describes the spinodal decomposition and modulated structures more adequately than Cahn＇s theory and its modifications.
