The book gives an overview of the dynamic behavior of dislocations and its relation to plastic deformation. It introduces the general properties of dislocations and treats the dislocation dynamics in some detail. Finally, examples are described of the processes in different classes of materials, i.e. semiconductors, ceramics, metals, intermetallic materials, and quasicrystals. The processes are illustrated by many electron micrographs of dislocations under stress and by video clips taken during in situ straining experiments in a high-voltage electron microscope showing moving dislocations. Thus, the users of the book also obtain an immediate impression and understanding of dislocation dynamics.
Aus den Rezensionen:
"... Das besondere an dem Buch ist jedoch, dass die ausführlich beschriebenen Experimente mit Videosequenzen ... Dieses Buch ist fraglos als Standardwerk anzusehen, das in keinem physikalisch-chemischen oder materialwissenschaftlichen Labour ... In verbindung mit dem reichhaltigen Videomaterial, eignet sich dieses Buch zudem, vortrefflich, Studenten in fortgeschrittenen Studiengängen die Versetzungsdynamik bei plastischer Verformung von Festkörpern in bisher nicht gekannter Weise zur Anschauung zu bringen.” (Dr.rer.nat.Armin Feldhoff, in: Elektronenmikroskopie, Heft 33, November 2011)

Klappentext
Very many structural materials like metals and ceramics are of crystalline nature.Undermostoftheconditions,theyundergoplasticdeformationbefore they fail under load. The plastic deformation is mediated by the gene- tion and motion of one-dimensional crystal defects, the so-called dislocations. Thus, the density and dynamic properties of the dislocations determine the plastic behavior of the respective materials and frequently also their failure. Thedislocationdynamics,that is,the responseofthedislocationsto anext- nal load, is controlled by the interaction between the moving dislocations with the periodic crystal lattice structure, other crystal defects from point defects oversmall clusters to largerprecipitates, with other dislocations fo- ing a microstructure through which the mobile dislocations have to move, and ?nally the grain and phase structure of the material. Considering these di?erent interactions, the dislocation motion turns out to be quite a complex process. In situ straining experiments in a transmission electron microscope are a powerful means for studying the microprocesses controlling the dislocation mobility. With this method, dislocations candirectly be observedduring their motionunderload.Thetechniqueadvancedwhenhigh-voltageelectronmic- scopes became commercially available at the end of the 1960s, ?rst in Japan and later on also in other countries. These microscopes enable the transm- sion of thicker specimens, which have properties similar to macroscopic bulk specimens.Besides,they o?ersu?cientroomfor elaboratedeformationstages in the specimen chamber. In the last 30 years, in situ straining experiments were performed on many materials, both in conventional and in high-voltage electron microscopes. The present author and his coworkers performed such experiments over about 30 years, yielding many hours of video recordings of dislocation motion.
