Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present work deals with stress redistributions and their subsequent influence on the precipitation in NiTi based shape memory alloys. Two mechanisms which may result into the stress redistribution are selected. The calculations based on the linear elasticity theory are performed using three simple models of microstructures with increasing complexity. The obtained results clearly show that the selected mechanisms give rise to the stress redistribution in the microstructures. The interaction energy between redistributed stress field and the precipitate-matrix misfit strain is calculated. The selection of crystallographic precipitate variants as a result of the minimum interaction energy criterion is demonstrated. A comparison of the calculated results with the experimental data suggests that it is possible to explain qualitatively the selective precipitation by means of the mechanisms of stress redistributions. The concepts described here are general, and can be easily adopted for modelling other strain/stress problems in polycrystalline materials. 100 pp. Englisch.

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The scope of this book ranges from a continuum theory of dislocations treated within the linear elasticity theory, connects the continuum and atomistic level modelling in discussing the critical thickness of thin epitaxial layers, and covers some issues related to the electronic structure of III-nitride alloys by means of the ab initio methods. The topics discussed in the first part aim (i) to apply general elasticity approaches known from the literature to the specific case of wurtzite materials, (ii) to extend equilibrium heteroepitaxial critical thickness models to III-N systems, and (iii) to develop an improved geometrical model for threading dislocation density reduction during the growth of thick GaN films. The second part of the book employs the density functional theory (iv) to investigate the electronic structure of III-N compounds and correlate these with experimentally available N K-edge electron energy loss near edge structure (ELNES) data, (v) to apply the special quasi-random structures to ternary III-N aiming to develop a methodology for modelling wurtzite alloys with a quantitative agreement with experiment, and (vi) to discuss strain effects on ELNES.
