Ultrafine Grained Materials Iv

This book addresses all aspects of the science and technology of ultrafine grained materials produced by Severe Plastic Deformation (SPD) techniques. It presents fundamental issues in SPD processing and SPD-processed materials, processing and microstructures, microstructural evolution, mechanical and physical properties, superplasticity, computational and analytical modeling, new SPD technologies and advances, and structural applications. From the 2006 TMS Annual Meeting, held March 12-16, 2006, in San Antonio, Texas.

Volume is indexed by Thomson Reuters CPCI-S (WoS). The present volume contains 175 selected papers from the 4th International Conference on Ultrafine-Grained and Nano-structured Materials (UFGNSM2013). This is the fourth biennial conference in UFGNSM series, jointly organized by Center of Excellence for High Performance Materials (CEHPM), University of Tehran, IRAN and University of Patras, GREECE. This volume presents a selection of papers submitted to the conference from universities and industries. These papers cover various aspects of ultrafine grained and nanostructured materials including: novel approaches to produce ultrafine grained and nanostructured materials and related properties, nanoparticles processing, nanostructure control, nanocomposites, nanocoatings and thin films, ultrafine grains and nanostructures characterization, simulation and modeling, and energy applications.

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

Proceedings of a symposium sponsored by the Shaping and Forming Committee of the Materials Processing and Manufacturing Division (MPMD) and the Mechanical Behavior Committee (Jt. SMD/ASM-MSCTS) of the Structural Materials Division (SMD) of TMS (The Minerals, Metals & Materials Society) and held during the 2002 TMS Annual Meeting in Seattle, Washington February 17-21,2002.

Superplasticity and Grain Boundaries in Ultrafine-Grained Materials, Second Edition, provides cutting-edge modeling solutions surrounding the role of grain boundaries in processes such as grain boundary diffusion, relaxation and grain growth. In addition, the book's authors explore the formation and evolution of the microstructure, texture and ensembles of grain boundaries in materials produced by severe plastic deformation. This updated edition, written by leading experts in the field, has been revised to include new chapters on the basics of nanostructure processing, the influence of deformation mechanisms on grain refinement, processing techniques for ultrafine-grained and nanostructured materials, and much more. Provides practical applications and methods for the proper implementation of models, allowing for more effective complex metal forming processes Features new chapters on the microstructure, mechanical behavior and functional properties of HCP metals, processing ultrafine-grained and nanostructured materials, and more Covers experimental assessment and computational modeling techniques for adiabatic heating and saturation of grain refinement during SPD of metals and alloys

The book discusses a number of problems associated with grain boundaries in polycrystals and other topics of interest to metallurgists and researchers concerned with the problems of nanomaterials. and nanotechnology.
