SFB 422:  Strukturbildung und Eigenschaften in Grenzschichten

Subject Area Thermal Engineering/Process Engineering
Term from 1997 to 2001
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5480297
 
The research project is focused on the kinetics of structure evolution and properties of nanoscale materials of multicomponent metallic systems with limited miscibility. One of the main topics of the project is the investigation of the magnetic and mechanical behavior of interlayers in such materials. Structural, compositional and morphological transformations in connection with property changes are investigated by an interdisciplinary team joining research groups from materials science, physics and electric engineering. Various methods of nanoscale structure preparation are studied: multilayer formation using pulsed laser deposition, sputtering, ion implantation and ion mixing, as well as rapid cooling of metal melts. By applying a large spectrum of high resolution analytical techniques of solid state physics, the peculiarities of the kinetics of structure transitions on the nanoscale are studied, as for example the formation of amorphous and new metastable phases, morphological instabilities of layered structures, and nanoscale precipitations in a supersaturated solid solution. Special metal alloys have been selected corresponding to the particular fundamental questions: magnetotransport (especially the giant magnetoresistance), multicomponent metallic bond layers for ferroelectric thin films, diffusion barriers for microelectronic structures, and metastable precursor systems of intermetallics with interesting mechanical behavior.
