Book excerpt: In der vorliegenden Dissertation wurden neue Erkenntnisse auf dem Gebiet der experimentellen Erforschung der Korngrenzenbewegung vorgestellt. Im Rahmen der Arbeit wurde anhand von in-situ Messungen mittels einer eigens dazu entwickelten Polarisationsmikroskopiesonde mit integriertem Heiztisch die Abhängigkeit der Korngrenzenbeweglichkeit vom Desorientierungs- und Inklinationswinkel der Korngrenze, sowie der Temperatur an speziell gezüchteten Bikristallen aus 99,995% Zink mit symmetrischen und asymmetrischen Kippkorngrenzen und gemischten Korngrenzen im Temperaturbereich zwischen 330°C und 415°C in Hochmagnetfeldern von 10 bis 28 Tesla Stärke als Triebkraft untersucht. Dabei wurde die jeweilige Wanderungsgeschwindigkeit v der Korngrenzen bei verschiedenen Temperaturen und treibenden Kräften gemessen. Aus den so erhaltenen Messdaten wurden die Aktivierungsparameter der Korngrenzenbewegung für die jeweils untersuchte Korngrenze bestimmt.Weiter wurde im Rahmen der Experimente in Hochfeldmagneten gezeigt, dass die Polarisationsmikroskopiesonde zur Bestimmung der Korngrenzenenergie in magnetisch anisotropen Metallen verwendet werden kann. Zu kleinerem Anteil wurden auch Versuche zu krümmungsgetriebener Korngrenzenbewegung durchgeführt. Alle Ergebnisse zeigten eine starke Inklinations- und Desorientierungsabhängigkeit der Korngrenzenbeweglichkeit, wobei für asymmetrische Korngrenzen höhere Aktivierungsparameter ermittelt wurden als für symmetrische. Dies wurde auf Unterschiede zwischen der atomistischen Struktur von asymmetrischen und symmetrischen Korngrenzen zurückgeführt. Weiterhin wurde auch die Auswirkung einer Glühung im Hochmagnetfeld auf Textur- und Mikrostrukturentwicklung von Zinkpolykristallen untersucht, wobei gezeigt wurde, dass das Magnetfeld ein geeignetes Werkzeug zur Beeinflussung der Mikrostruktur in Zink ist.

This book was released on 2005-07-27 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processing in magnetic fields is a rapidly expanding research area with a wide range of promising applications in materials science, development and design. Numerous research centers dedicated to materials research and processing in magnetic fields have been created around the world. This volume brings together contributions from these centers to review the most recent activities in this field.The papers in this book cover a broad spectrum of research of the effects on magnetic fields in materials processing. The cutting-edge research topics include magnetic levitation of diamagnetic matter and its applications; anisotropy, used for aligning fibers, polymers, and carbon nanotubes; texturing of materials during a phase transition, in both liquid-to-solid and solid-to-solid state transitions; grain boundary migration and mobility changes, giving us a perspective for texture development in metals; and the damping effect of magnetic fields on conductive liquids, which has been exploited for improved crystal growth quality. Of growing interest are the effects of magnetic fields in biology, and their beneficial applications for medical treatments.

Book excerpt: Texture is a fundamental material characteristic which results from the microstructural evolution that takes place during various processes, including the thermomechanical deformation of materials. Therefore, texture-related phenomena will continue to be of great importance, because of their scientific interest as well as their effect upon industrial applications, in the 21st century. This volume deals with all of the themes which are related to texture phenomena in both conventional and advanced materials, including: ceramics, thin films, polymers, nanocrystalline materials, rocks and composites. The papers cover various texture-related fields: quantitative texture analysis, experimental measurement, modeling, micro-texture analysis, deformation textures, recrystallization and grain growth textures, anisotropic properties, textures in steels, textures in Al and Al-Alloys, textures in thin films, and textures in ceramics, intermetallics and polymers, etc.
