Soft Magnetic Composites (SMCs) typically consist of large iron particles coated with a fairly thin inorganic layer. The combination of soft particles with a brittle layer causes, however, a rather poor mechanical behaviour of the SMCs. The particle boundaries of the specific SMC Somaloy 700 3P can be classified into four different types according to the complexity of their layers. Tests on both micro- and macroscale showed that the particle-boundary interface is critical in terms of failure.

In this work experimental tests are performed to investigate the forming behavior of unidirectional non-crimp fabrics (UD-NCFs) within the context of an automated preforming process. Based on the experimental results, a macroscopic forming simulation model for UD-NCFs is developed and model parameters are identified via the simulation of material tests. The forming simulation model is validated via hemisphere and car body part forming tests.

Mixed ionic-electronic conducting (MIEC) ceramics as oxygen transport membranes (OTMs) can provide high oxygen permeation rates at comparably low energy demands. For this purpose, Ba?.?Sr?.?Co?.?Fe?.?O??? (BSCF) shows the best performance under ideal operating conditions. Thermal and chemical stability investigations, electrical behavior ?(T,pO?,t), and oxygen exchange parameter extraction by means of electrical conductivity relaxation resulted in a far better understanding of the BSCF system.

The state of the art in the optical characterization of materials is advancing rapidly. New insights have been gained into the theoretical foundations of this research and exciting developments have been made in practice, driven by new applications and innovative sensor technologies that are constantly evolving. The great success of past conferences proves the necessity of a platform for presentation, discussion and evaluation of the latest research results in this interdisciplinary field.

Jurij Karlovič Oleša war einer der bedeutenden Schriftsteller der frühen Sowjetzeit, jener in literarischer Hinsicht lebendigsten Periode, nämlich der 20ger Jahre. Tiefgehenden und vielseitigen Einblick gerade in diese neuere (wie auch die neueste) russische Literatur, ebenso wie belebteres Verständnis für literaturtheoretische Betrachtungsweisen vermittelte mir Professor Dr. Wolfgang Kasack, dem ich auch für die entscheidende Anregung zu der Dissertation und die wertvollen Hinweise während der Arbeit zu grösstem Dank verpflichtet bin. Die Arbeit wurde gefördert durch ein Promotionsstipendium der Universität Köln, in dessen Rahmen zwei Aufenthalte in der Sowjetunion es erlaubten, in Deutschland nicht zugängliche Literatur miteinzubeziehen. Durchsuchbare elektronische Faksimileausgabe als PDF. Digitalisiert im Rahmen des DFG-Projektes Digi20 in Kooperation mit der BSB München. OCR-Bearbeitung durch den Verlag Otto Sagner.
