These proceedings comprise the papers presented at the international conference on 'Diffusion in Materials (DIMAT-96)' held at Schloss Nordkirchen, Germany, August 1996 - the largest international diffusion conference so far held. The two-volume set therefore covers a very broad spectrum of topics. From the materials point of view, metals, alloys, intermetallics, elemental and compound semiconductors, amorphous materials, nonmetals such as fast ionic conductors, oxides, nitrides, polymers and even melts were discussed.
