Available in PDF, EPUB and Kindle. Book excerpt: Materials with metastable structures and microstructures have been used with success to create unusual structural and functional properties and property combinations. Highly nonequilibrium technologies for creating metastable materials have been devised which allow materials to be prepared far away from the thermodynamic equilibrium. Using these methods, materials can now be designed to possess specific properties tailored to fit an application, rather than fitting an application to the properties of available materials. However, as these materials are metastable with respect to structural and compositional changes under temperature, there is great concern for understanding and controlling their limitations. This book features both fundamental as well as applied aspects of the subject by stressing the structure/property relationships, the conditions for stability of these materials, and the requirements for technological applications. In addition to the synthesis, processing, characterization, properties, and applications of such materials, attention is also focused on the modelling of structures, phenomena and processes. Topics include: synthesis and processing; thermodynamic and kinetics; phase transformations and properties and applications.

Download or read book Stability of Microstructure in Metallic Systems written by J. W. Martin and published by Cambridge University Press. This book was released on 1997-03-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this textbook, popular amongst students and faculty alike, investigates the various causes of thermodynamic instability in metallic microstructures. Materials theoretically well designed for a particular application may prove inefficient or even useless unless stable under normal working conditions. The authors examine current experimental and theoretical understanding of the kinetics behind structural change in metals. The entire text has been updated in this new edition, and a completely new chapter on highly metastable alloys has been added. The degree to which kinetic stability of the material outweighs its thermodynamic instability is very important, and dictates the useful working life of the material. If the structure is initially produced to an optimum, such changes will degrade the properties of the material. This comprehensive and well-illustrated text, accompanied by ample references, will allow final year undergraduates, graduate students and research workers to investigate in detail the stability of microstructure in metallic systems.

This book was released on 2006 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In this work, microstructure evolution of an Al-3Mg-0.4Cu-0.12Si (wt%) alloy was studied during artificial aging at 180°C and 200°C. The primary investigation methods used were conventional and high resolution transmission electron microscopy (TEM and HRTEM), Z-contrast scanning TEM, and atom probe tomography (APT). Two new metastable phases are found to successively form during 180°C aging, designated as GPB and GPBII zones. The first forming GPB zones are rod-like regions aligned along 100Al directions. As supported by ab initio calculation, the GPB zones are L10 ordered, with alternating Mg enriched and Si, Cu, Al enriched layers. In the later stages of aging, GPBII are detected as nanometer size-scale, homogeneously dispersed, coherent particles. The crystal structure of the GPBII can be explained by a hexagonal lattice, with parameters a=0.7, c=0.4nm and space group P6̄2m. The stoichiometry of the proposed GPBII zone is Al3Mg3Si2Cu1, which in terms of the solute elements agrees with the elemental analysis. Ab initio calculations show very favorable enthalpy of formation of -14.4 kJ/mol. At higher temperature aging and longer aging times, such as 16 hours at 200°C, the microstructure is found to consist of two different crystallographic types of GPBII zones, which can be differentiated based on their location in the matrix. The isolated GPBII zones are comparable to those from lower temperature aging; however, the GPBII zones associated with S-phase particles have a different crystal structure, which seem to be crystallographically related to the structure of lath-like particles in some 6xxx series alloys. At the later stages of aging, the structure also consists of isolated S-phase particles, which have a rod-like morphology and modified orientation relationship (S''-phase). The origin of the modified orientation relationship for S''-phase was studied. It is found that its establishment is related to coherency at the (021)S//(014)Al interface, which is shown to coexist with the commonly present (001)S//(021)Al. Apart from the microstructural studies, attention was paid to the mechanical properties of alloys of similar composition from various aging treatments. The observed strengthening from the early stages of aging was modeled based on a contribution from GPB zones considering three different mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: Treatise on Materials Science and Technology, Volume 7: Microstructures of Irradiated Materials covers the effects of irradiation on the microstructures of solids. The book introduces basic concepts and terminology and discusses the physical effects of irradiation, those having to do with the physical displacement of atoms and the subsequent atom rearrangements that can occur either by momentum transfer or by diffusional phenomena. The text also describes the chemical effects of irradiation, including diffusion, phase changes, precipitation of solute atoms, transmutations, and combinations of these. Some of the complex situations encountered in some nuclear fuels and structural materials of practical concern are also encompassed. Metallurgists, metallurgical engineers, ceramists, materials scientists, and people interested in the nuclear field will find the book invaluable.

Download or read book Metallography and Microstructure in Ancient and Historic Metals written by David A. Scott and published by Getty Publications. This book was released on 1992-01-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.

Download or read book Rapidly Quenched Metals written by S Steeb and published by Elsevier. This book was released on 2012-12-02 with total page 1163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapidly Quenched Metals, Volume I covers the proceedings of the Fifth International Conference on Rapidly Quenched Metals, held in Wurzburg, Germany on September 3-7, 1984. The book focuses on amorphous and crystalline metals formed by rapid quenching from the melt. The selection first covers the scope and trends of developments in rapid solidification technology, rapid solidification, and undercooling of liquid metals by rapid quenching. Discussions focus on experimental method, powders, strip, particulate production, consolidation, and alloys and alloy systems. The text then examines the solidification of undercooled liquid alloys entrapped in solid; crystallization kinetics in undercooled droplets; and grain refinement in bulk undercooled alloys. The manuscript tackles the undercooling of niobium-germanium alloys in a 100 meter drop tube; influence of process parameters on the cooling rate of the meltspinning process; and the mechanism of ribbon formation in melt-spun copper and copper-zirconium. The formation and structure of thick sections of rapidly-solidified material by incremental deposition and production of ultrafine dispersions of rare earth oxides in Ti alloys using rapid solidification are also mentioned. The selection is a valuable reference for physicists, chemists, physical metallurgists, and engineers.
Download or read book Metallurgy and Design of Alloys with Hierarchical Microstructures written by Krishnan K. Sankaran and published by Elsevier. This book was released on 2017-06-14 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgy and Design of Alloys with Hierarchical Microstructures covers the fundamentals of processing-microstructure-property relationships and how multiple properties are balanced and optimized in materials with hierarchical microstructures widely used in critical applications. The discussion is based principally on metallic materials used in aircraft structures; however, because they have sufficiently diverse microstructures, the underlying principles can easily be extended to other materials systems. With the increasing microstructural complexity of structural materials, it is important for students, academic researchers and practicing engineers to possess the knowledge of how materials are optimized and how they will behave in service. The book integrates aspects of computational materials science, physical metallurgy, alloy design, process design, and structure-properties relationships, in a manner not done before. It fills a knowledge gap in the interrelationships of multiple microstructural and deformation mechanisms by applying the concepts and tools of designing microstructures for achieving combinations of engineering properties—such as strength, corrosion resistance, durability and damage tolerance in multi-component materials—used for critical structural applications. Discusses the science behind the properties and performance of advanced metallic materials Provides for the efficient design of materials and processes to satisfy targeted performance in materials and structures Enables the selection and development of new alloys for specific applications based upon evaluation of their microstructure as illustrated in this work
Download or read book Cathodic Arcs written by André Anders and published by Springer Science & Business Media. This book was released on 2009-07-30 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cathodic arcs are among the longest studied yet least understood objects in science. Plasma-generating, tiny spots appear on the cathode; they are highly dynamic and hard to control. With an approach emphasizing the fractal character of cathode spots, strongly fluctuating plasma properties are described such as the presence of multiply charged ions that move with supersonic velocity. Richly illustrated, the book also deals with practical issues, such as arc source construction, macroparticle removal, and the synthesis of dense, well adherent coatings. The book spans a bridge from plasma physics to coatings technology based on energetic condensation, appealing to scientists, practitioners and graduate students alike.
