This book was released on 2009 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal stability of nanocrystalline materials has been studied extensively in recent years for a wide spectrum of materials. Specifically, electrodeposited nanocrystalline nickels has shown dramatic sensitivity in its growth behaviour to sulphur impurity concentrations in the range of hundred parts per million. In the current study, a novel approach to eleetrodeposition utilizing strong mechanical agitation and unusually high pulse deposition current densities was developed to produce nanocrystalline nickel with low sulphur content from an additive-free electrolyte. Inductively coupled plasma analysis showed that the sulphur impurity content was less than 10 ppm. Isothermal heat treatments of this material at three annealing temperatures of 285°C, 350°C and 450°C showed no strong evidence of abnormal grain growth, a growth form observed in many past studies on sulphur-containing nanocrystalline nickel. The microstructure evolution was classified via the introduction of log-time distribution histograms, and cumulative volume fraction diagrams. The activation energy and kinetics for grain growth was determined.

From the contents: Bulk Crystals, Three-Dimensional Lattices - Crystal Layers, Two-Dimensional Lattices, Symmetry - Ideal Single Crystal Surfaces - Real Crystal Surfaces - Adsorbate layers - Interference Lattices - Chiral Surfaces - Experimental Analysis of Real Crystal Surfaces - Nanoparticles and Crystallites - Quasicrystals - Nanotubes
Download or read book Investigating the Thermal and Phase Stability of Nanocrystalline Ni W Produced by Electrodeposition Sputtering and Mechanical Alloying written by Christopher Jonathan Marvel and published by . This book was released on 2016 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The findings of this research will hopefully guide future efforts to design more thermally stable nanocrystalline alloys. The link between phase stability and grain growth behavior of Ni-W was thoroughly discussed, as well as the dependence of bulk fabrication processing on the contamination found in the alloys. Ultimately, this research has greatly expanded the general understanding of nanocrystalline Ni-W microstructures, and it is likely that similar phenomena occur in other nanocrystalline systems.
Download or read book Defect Structure and Properties of Nanomaterials written by J Gubicza and published by Woodhead Publishing. This book was released on 2017-03-05 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defect Structure and Properties of Nanomaterials: Second and Extended Edition covers a wide range of nanomaterials including metals, alloys, ceramics, diamond, carbon nanotubes, and their composites. This new edition is fully revised and updated, covering important advances that have taken place in recent years. Nanostructured materials exhibit unique mechanical and physical properties compared with their coarse-grained counterparts, therefore these materials are currently a major focus in materials science. The production methods of nanomaterials affect the lattice defect structure (vacancies, dislocations, disclinations, stacking faults, twins, and grain boundaries) that has a major influence on their mechanical and physical properties. In this book, the production routes of nanomaterials are described in detail, and the relationships between the processing conditions and the resultant defect structure, as well as the defect-related properties (e.g. mechanical behavior, electrical resistance, diffusion, corrosion resistance, thermal stability, hydrogen storage capability, etc.) are reviewed. In particular, new processing methods of nanomaterials are described in the chapter dealing with the manufacturing procedures of nanostructured materials. New chapters on (i) the experimental methods for the study of lattice defects, (ii) the defect structure in nanodisperse particles, and (iii) the influence of lattice defects on electrical, corrosion, and diffusion properties are included, to further enhance what has become a leading reference for engineering, physics, and materials science audiences. - Provides a detailed overview of processing methods, defect structure, and defect-related mechanical and physical properties of nanomaterials - Covers a wide range of nanomaterials including metals, alloys, ceramics, diamond, carbon nanotubes, and their composites - Includes new chapters covering recent advances in both processing techniques and methods for the study of lattice defects - Provides valuable information that will help materials scientists and engineers highlight lattice defects and the related mechanical and physical properties

Download or read book Advanced Topics on Crystal Growth written by Sukarno Ferreira and published by BoD – Books on Demand. This book was released on 2013-02-20 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystal growth is the key step of a great number of very important applications. The development of new devices and products, from the traditional microelectronic industry to pharmaceutical industry and many others, depends on crystallization processes. The objective of this book is not to cover all areas of crystal growth but just present, as specified in the title, important selected topics, as applied to organic and inorganic systems. All authors have been selected for being key researchers in their field of specialization, working in important universities and research labs around the world. The first section is mainly devoted to biological systems and covers topics like proteins, bone and ice crystallization. The second section brings some applications to inorganic systems and describes more general growth techniques like chemical vapor crystallization and electrodeposition. This book is mostly recommended for students working in the field of crystal growth and for scientists and engineers in the fields of crystalline materials, crystal engineering and the industrial applications of crystallization processes.

Download or read book Grain Boundary Migration in Metals written by Gunter Gottstein and published by CRC Press. This book was released on 1999-06-17 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavior of adjacent materials at the boundary where they meet is an essential aspect of creating new engineering materials. Grain Boundary Migration in Metals is an authoritative account of the physics of grain boundary motion, written by two highly respected researchers. They provide a comprehensive overview of current knowledge regarding the migration process and how it affects microstructure evolution, focusing their treatment exclusively on the properties and behavior of grain boundaries with well defined geometry and crystallography. With their emphasis on applications-such as the characterization of microstructure and texture, recrystallization, and grain growth-the authors effectively fill the gap between the physics of grain boundary motion and its engineering practicality. The need for better microstructural design motivates permanent thrust for research in the field, and continued rapid progress appears inevitable. Grain Boundary Migration in Metals provides a solid foundation in the phenomena and serves as a valuable reference for professionals in materials science, solid state physics, and any industry engaged in metals production and the heat treatment of metals and alloys.
