Bøger af Goerg H. Michler

Um das mechanische Verhalten von Werkstoffen einerseits besser zu verstehen und andererseits gezielt verbessern zu können, müssen die Prozesse und Mechanismen, die bei mechanischer Belastung im Material in Abhängigkeit von den Materialstrukturen ablaufen (die sog. ¿Struktur- Eigenschafts-Korrelationen¿), bekannt sein. Grundlegend sind die Prozesse auf mikro- und nanoskopischer Größenebene, d.h. im Größenbereich von 0,1 mm bis herab zu 0,1 nm (d.h. sog. Mikro- und Nanomechanik). Der Autor charakterisiert anschaulich diese mikro- und nanomechanischen Mechanismen mit aussagefähigen Schemata und Bildern auf der Grundlage hauptsächlich von elektronenmikroskopischen Analysen. Neben allgemeingültigen Prozessen und Mechanismen wird auch auf materialspezifische Effekte (z.B. Crazes, Chevrons, Dünnschichtfließen) eingegangen.Die Produktfamilie WissensExpress bietet Ihnen Lehr- und Lernbücher in kompakter Form. Die Bücher liefern schnell und verständlich fundiertes Wissen.

Goerg Michler summarizes the large field of electron microscopy and clearly presents the different techniques. The author clearly describes the possible applications of microscopy and the requirements for specimen preparation. He illustrates the descriptions with picture examples from practice.The Author:Prof. Dr. rer. nat. habil. Goerg H. Michler was head of the Institute for Materials Science at Martin Luther University Halle-Wittenberg, is honorary chairman of the Institute for Polymer Materials e.V. and chairman of the Heinz Bethge Foundation for Applied Electron Microscopy.

The book brings together the detailed knowledge of structure and morphology of the main classes of polymers, including commodities as well as special polymers, with explanation of the mechanical properties, processes, and mechanisms on macroscopic, microscopic, and nanoscopic scales. Description, explanation, and theoretical interpretation of all of the micro- and nanoscopic processes and mechanisms in different polymers constitute the central part the book. Thus, it offers a key for a better understanding of structure-property correlations of nearly all polymers of interest in industrial applications. A central aim of the book is to show how, by changing the morphology, microprocesses and, finally, the mechanical properties can be improved. There is no other book available on the market which is focused on micromechanical processes of polymers and their role to improve the properties of polymeric materials.

Structure and morphology determine the properties of polymeric materials. This atlas provides, with over 2,000 high-quality micrographs, a comprehensive overview of the structural/morphological diversity of all classes of plastics. All microscopic techniques from light microscopy through scanning and transmission electron microscopy to atomic force microscopy are covered.

The study of polymers by electron microscopy (EM) needs special techniques, precautions and preparation methods, including ultramicrotomy. General characteristics of the different techniques of EM, including scanning force microscopy, are given in this hands-on book.
