Books by Keyword: Grain Boundary Sliding (GBS)

Description: Interest in the phenomenon of superplasticity has been increasing steadily, both from the viewpoint of fundamental scientific understanding as well as of industrial application. The scope of superplasticity has also broadened materials-wise, and now includes, in addition to metals: intermetallics, ceramics, bulk metallic glasses, nanostructured materials and composites. The objective of this special collection was to provide an international forum through which to gather up-to-date knowledge and information on a wide range of topics and to encourage further developments in superplasticity. Over 64 peer-reviewed papers have been selected for publication.
Volume is indexed by Thomson Reuters CPCI-S (WoS).
The volume is divided into the following chapters: Mechanisms of Superplasticity, Superplastic Materials, Design, Testing and Modelling, Processing, Industrial Applications. Altogether, the contents constitute a timely and invaluable guide to the state-of-the-art of superplasticity.

Bulk nanostructured (NS) materials have emerged as a new class of materials having unusual structures and properties. As a result, they have attracted considerable attention in recent years. Bulk NS materials are single or multi-phase polycrystals with a nanoscale grain size and can usually be classified into nanocrystalline (<100nm) and ultrafine grain (<1000nm) materials. This book contains important papers on the mechanical properties and deformation mechanisms of bulk NS materials. The advanced properties include strength, ductility, strain-hardening, fatigue, dynamic, creep and toughness, etc. These properties are important for the ultimate structural applications of bulk NS materials. The mechanical properties of these materials are determined by their specific deformation mechanisms (such as boundary-dominated deformation) due to the very small grain size in comparison with coarse-grained counterparts. The 20 invited papers is divided between two chapters: I. Advanced Mechanical Properties of Nanostructured Materials - II. Deformation Mechanisms of Bulk Nanostructured Materials. This work should be read by all of those wishing to improve mechanical properties without having to consider entirely new alloys.

Description: The original use of superplastic materials involved mainly applications involving aluminium and titanium. However, discoveries made all over the globe have led to the development of superplastic ceramics, intermetallics, nano-materials, plastics, glasses and other substances.

Strength and ductility are two of the most important mechanical properties of structural materials, but this usually involves a trade-off, because of the fundamental inverse proportionality of these two features. Since the 1980s, bulk nanostructured materials have emerged as a new class of material having unusual structures and, as a result, have attracted increasing attention. Unfortunately, most bulk nanostructured materials still do not evade the strength-ductility trade-off dilemma, and usually have very poor ductility. The poor ductility of bulk nanostructured materials has indeed become a seemingly insurmountable obstacle to the widespread technological application of structural bulk nanostructured materials.

Description: Nanostructured materials, in which the structural features (e.g., grains and/or domains separated by low-angle grain boundaries) are smaller than 100nm in at least one dimension, have attracted worldwide research interest for more than a decade because of their unique properties. For example, the combination of high strength with high ductility has been reported for some nanostructured metals and alloys: this is a rare, if not impossible, combination of mechanical properties for coarse-grained metals and alloys. Among the many techniques available for producing nanostructured materials, severe plastic deformation (SPD) is the most popular and most rapidly developing one.

Superplastic forming (SPF) has come a long way from its relatively recent history of being of interest only to the aerospace and aeronautical industries, and has made rapid inroads into applications in the automotive, rail, architectural, sports, dental and entertainment sectors.

Description: From once being of interest only to the aerospace and aeronautical ndustries, superplastic forming (SPF) has recently made inroads into the automotive, rail, architectural, sports, dental and entertainment sectors. However, due to a number of problematic technological issues ranging from die-material selection, die design, surface finish (e.g. alpha casing), differential thinning, temperature-pressure-time cycle determination and overall economy, the application of superplasticity has reached nowhere near its full potential.

Recent research on the creep and fracture of engineering materials is presented, with particular emphasis being placed on: mechanisms of high-temperature deformation and fracture, materials for high-temperature service, the behavior of single and polycrystals, components and structures, grain boundaries and interfaces, and superplasticity.

The application of ceramic materials is currently expanding into a wide range of areas, e.g. gas turbine assembly, engine components, electronic devices, bio-materials etc. But because ceramics pose problems with respect to their brittleness and low reliability, due to their intrinsic nature and/or processing defects, research related to the deformation and fracture of ceramics is still a subject of high priority.

The papers of this second conference summarize the progress made in three major target areas; (1) to identify new phenomena in superplasticity, (2) to extend superplasticity research into the atomistic level of grain boundary analysis and (3) to find ways of enhancing collaboration between scientists and industrial engineers.
