Superplasticity and Grain Boundaries in Ultrafine-Grained Materials by Peter M. Burgess,A I Pshenichnyuk Pdf

Superplasticity is a state in which solid crystalline materials, such as some fine-grained metals, are deformed well beyond their usual breaking point. The phenomenon is of importance in processes such as superplastic forming which allows the manufacture of complex, high-quality components in such areas as aerospace and biomedical engineering. Superplasticity and grain boundaries in ultrafine-grained materials discusses a number of problems associated with grain boundaries in metallic polycrystalline materials. The role of grain boundaries in processes such as grain boundary diffusion, relaxation and grain growth is investigated. The authors explore the formation and evolution of the microstructure, texture and ensembles of grain boundaries in materials produced by severe plastic deformation. Written by two leading experts in the field, Superplasticity and grain boundaries in ultrafine-grained materials significantly advances our understanding of this important phenomenon and will be an important reference work for metallurgists and those involved in superplastic forming processes. Discusses significant problems associated with grain boundaries in polycrystals incorporating structural superplasticity and grain boundary sliding Assesses the role of grain boundaries in processes such as grain boundary diffusion, relaxation and grain growth Explores the formation and evolution of the microstructure, texture and ensembles of grain boundaries in materials produced by severe plastic deformation

Superplasticity and Grain Boundaries in Ultrafine-Grained Materials by Aleksandr Petrovich Zhilyaev,A I Pshenichnyuk Pdf

The book deals with a number of problems associated with the description and experimental verification of the individual boundaries and ensembles of the grain boundaries in polycrystals. The role of these boundaries in processes such as grain boundary diffusion, relaxation and grain growth is investigated. It is attempted to construct a general model of superplasticity based on the experimentally determined relationships relating to the bands of co-operative grain boundary sliding. Special attention is given to the problems of formation and evolution of the microstructure, the texture and ensembles of the grain boundaries in materials produced by severe plastic deformation methods.

Overview on Superplasticity Research on Small-grained Materials by Anonim Pdf

Superplasticity is generally associated with fine grains, grain boundary sliding, and high tensile ductility at elevated temperature. This paper reviews some of the recent important findings in fine-grained superplasticity, including the areas of superplastic ceramics and bf-high-strain-rate superplasticity (HSRS). Deformation mechanism maps are shown to be powerful tools for predicting the conditions where HSRS can be expected. Ultrafine grained materials, processed economically, remain an important objective in achieving HSRS. Threshold stresses, observed in fine-grained superplastic materials, are shown to be functions of temperature and grain size but their origin, however, remains obscure. Quasi-superplastic materials, with a strain-rate-sensitivity exponent of m = 0.33, are shown to have high elongations, and have considerable promise for netshape isothermal forming of sheet and bulk components.

Superplastic Forming of Advanced Metallic Materials by G Giuliano Pdf

Ultra fine-grained metals can show exceptional ductility, known as superplasticity, during sheet forming. The higher ductility of superplastic metals makes it possible to form large and complex components in a single operation without joints or rivets. The result is less waste, lower weight and manufacturing costs, high precision and lack of residual stress associated with welding which makes components ideal for aerospace, automotive and other applications. Superplastic forming of advanced metallic materials summarises key recent research on this important process. Part one reviews types of superplastic metals, standards for superplastic forming, processes and equipment. Part two discusses ways of modelling superplastic forming processes whilst the final part of the book considers applications, including superplastic forming of titanium, aluminium and magnesium alloys. With its distinguished editor and international team of contributors, Superplastic forming of advanced metallic materials is a valuable reference for metallurgists and engineers in such sectors as aerospace and automotive engineering.

This book combines the perspectives of materials science of Superplasticity, on the one hand, and those of design and mechanics, on the other, in order to provide a holistic view of materials, design, mechanics and performance which will lead to useful solutions of societal benefits, in addition to providing great intellectual challenges. After considering the experimental evidence for superplasticity in different classes of materials, the book discusses the physics-based models, along with their advantages and limitations. Then, the analyses for superplastic forming available in the framework of continuum mechanics, finite element analysis and numerical simulations are presented. Finally, the authors highlight some successful industrial applications. This book is recommended as a text book for courses on Superplasticity and as supplementary use for courses on Materials Processing, Manufacturing, High Temperature Deformation, Nanotechnology and Mechanical Behavior of Materials. Persons working in Department of Materials Science and Engineering, Physics, Mechanics, Mechanical Engineering, Aerospace Engineering, Metallurgy, Ceramics and Geo-sciences are likely to find the book to be useful. It is also recommended as a reference source for practicing engineers involved in the design, processing and manufacture of industrial components, which exploit the unique properties associated with superplastic materials.

Superplasticity of Alloys, Intermetallides and Ceramics by Oscar A. Kaibyshev Pdf

Superplasticity is shown to be a universal phenomenon in materials ranging from metals and intermetallics to ceramics. Superplastic deformation facilitates the production of materials with specifically chosen properties. This is illustrated using the examples of Mg-, Al-, and Ti-based commercial alloys, steels, and superalloys. Some of the strenghts of this book are: the broad range of materials studied, the reduction of scientific results to a form suitable for the practitioner, a profound physical analysis of the phenomenon, a new approach to superplastic treatment as a kind of strain-heat treatment, the presentation of new data on superplastic flow and on production techniques of micro- and submicrocrystalline structures.
