Recently, it was reported that nanostructured materials processed under high pressure by HPT and ECAP have an extraordinary combination of both high strength and high ductility, which are two desirable, but rarely co-existing properties. These findings indicate that high-pressure is a critical factor that can be employed to process nanostructured materials with superior mechanical, and possibly also physical, properties. It is the objective of this workshop to review our current knowledge, identify issues for future research, and discuss future directions on the processing and properties of nanostructured materials via SPD techniques, with a special emphasis on high-pressure effects. The 42 peer-reviewed papers in this book cover areas of high pressure effect on the nanostructure and properties of SPD-processed materials, fundamentals of nanostructured materials, development of high-pressure SPD technologies for commercializations, recent advances of SPD technologies as well as applications and future markets of SPD-processed nanostructured materials.

The processing and mechanical behaviour of bulk nanostructured materials are one of the most interesting new fields of research on advanced materials systems. Many nanocrystalline materials possess very high strength with still good ductility, and exhibit high values of fatigue resistance and fracture toughness. There has been continuing interest in these nanomaterials for use in structural and biomedical applications, and this has led to a large number of research programs worldwide. This book focuses on the processing techniques, microstructures, mechanical and physical properties, and applications of bulk nanostructured materials, as well as related fundamental issues. Only since recently can such bulk nanostructured materials be produced in large bulk dimensions, which opens the door to their commercial applications.

Nanocrystalline Titanium discusses the features of nanocrystalline titanium production by various SPD methods, also comparing their microstructure and properties. The authors characterize the physical, chemical and mechanical properties of ultrafine grained titanium, indicating which are crucial for their application. Titanium alloys are characterized by high specific strength combined with excellent corrosion resistance, whereas the mechanical properties of pure (or commercial purity - CP) titanium are much lower. SPD methods are proving to be an effective way to increase strength, even to a level typical for structural titanium alloys. This book is useful for academics and professionals studying the behavior of metallic materials. Discusses various SPD techniques and their applications for titanium Previews the limitations of SPD methods for titanium, along with the problems that can be encountered during production Characterizes the physical, chemical and mechanical properties of ultrafine grained titanium and indicates which are crucial for its production applications

Seit 1959 versuche ich in Göttingen, Studierende der Physik nach dem V 01' examen für ein Aufbaustudium der Physikalischen Metallkunde zu interessieren. Diese Aufgabe stellt sich heute an vielen Hochschulen, denn allgemein hat sich der Beruf des Metallkundlers in der Forschung, der Entwicklung metallischer Werkstoffe und ihrer industriellen Produktion als sehr befriedigend und aus sichtsreich erwiesen. Nicht nur ist die Metall-Technik außerordentlich vielseitig und lädt zu wissenschaftlicher Durchdringung ein, sondern auch andere Bereiche der Festkörper-verarbeitenden Industrie benutzen unter der Überschrift" Werk stoffwissenschaften" (Materials Science) zunehmend metallkundliche Methoden, etwa bei keramischen Werkstoffen, Halbleitermaterialien, Kunststoffen usw. Für ein solches Berufsbild ist heute ein Grundstudium der Physik sehr geeignet, während Metallkundler früherer Jahrgänge häufig als Chemiker oder Maschinen bau-Ingenieure begonnen haben. Das Grundstudium der Physik bietet neben strengem mathematischen Rüstzeug verschiedene Vorlesungen und Praktika der Experimentalphysik sowie den theoretisch-physikalischen Kursus incl. der Quantentheorie. Im 5. und 6. Semester leiten Einführungsvorlesungen über Festkörperphysik in das Gebiet der Physikalischen Metallkunde über. Sie lehnen sich auch in Deutschland häufig an das Lehrbuch von Ch. Kittel [1.1] an.
