Aluminium Alloys And Composites

Aluminium (Al) is a metal of great importance because of its excellent corrosion resistance, high electrical and thermal conductivity, good reflectivity, and very good recycling characteristics. The properties of heat-treatable Al-alloys can be further enhanced by the inclusion of a reinforcing phase that increases the mechanical properties of the overall composite. This book is a comprehensive guide on the different types of aluminum alloys and the new advances that have been made in developing and manufacturing aluminum alloys and composites. This text provides a comprehensive overview of the processing, formability, and chemical composition of aluminum alloys and composites. Part One is focused on evaluating the types and properties of advanced aluminum alloys and composites, while Part Two explores characterization. The advantage of this book is that it provides a detailed review of major advances that have occurred in the development and application of aluminum alloys and composites while outlining a development strategy for these materials.

Aluminium is an engineering material of strategic importance in the current stage of Industry 4.0. This book discusses advanced composites based on aluminium alloys. It also describes pressure infiltration of gas with liquid aluminium, the mechanical synthesis of aluminium alloy powder and halloysite nanotubes (HNTs) or multi-wall carbon nanotubes (MWCNTs) consolidated by plastic deformation, selected optimization and prediction models, casting aluminium alloys containing zirconium, aluminium alloys subjected to high-speed extrusion of shapes, corrosion resistance of alloys containing lithium, machining conditions of alloys with copper and zinc additions, and more.

An expert exposition of the structural and mechanical properties of light alloys and composites, bridging the gap between scientists and industrial engineers in its consideration of advanced light materials, their structure, properties, technology and application. Includes basic problems of alloy constitution and phase transformations. The aluminium alloys are the main topic of the book, consideration being given to their properties, casting technology, thermomechanical treatment and structure. Attention is also given to the magnesium alloys, particularly those having rare earth metal constituents. Both commercial titanium alloys and intermetallic compounds are discussed, as are metallic composites. The latest engineering techniques are discussed in both theoretical and practical terms.

Aluminium alloys are among the most interesting materials being adopted for weight reduction and recycling benefits. The increasing importance of aluminium alloys over the years is due to their widespread use and applications in automotive, aerospace, food handling, building, heat exchange, and electrical transmission industries. Their high strength/weight ratio makes aluminium alloys useful for applications where simultaneous high strength and lightness are needed.This book provides a comprehensive review of the design and development of innovative aluminium alloys and composites. Chapters discuss manufacturing processes and applications and are heavily illustrated to make the concepts clear.

The major issue of energy saving and conservation of the environment in the world is being emphasized to us to concentrate on lightweight materials in which aluminium alloys are contributing more in applications in the twenty-first century. Aluminium and its related materials possess lighter weight, considerable strength, more corrosion resistance and ductility. Especially from the past one decade, the use of aluminium alloys is increasing in construction field, transportation industries, packaging purposes, automotive, defence, aircraft and electrical sectors. Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are recyclability and its abundant availability in the world. In general, aluminium and its related materials are being processed via casting, drawing, forging, rolling, extrusion, welding, powder metallurgy process, etc. To improve the physical and mechanical properties, scientists are doing more research and adding some second-phase particles in to it called composites in addition to heat treatment. Therefore, to explore more in this field, the present book has been aimed and focused to bridge all scientists who are working in this field. The main objective of the present book is to focus on aluminium, its alloys and its composites, which include, but are not limited to, the various processing routes and characterization techniques in both macro- and nano-levels.

Semi-solid metal (SSM) processing, as a viable alternative manufacturing route to those of conventional casting and forging, has not yet been fully exploited despite nearly half a century since its introduction to the metal industry. The slow pace of adopting SSM routes may be due to various reasons, including capital costs, profit margins, and, most importantly, the lack of detailed analysis of various SSM processes in open literature to confidently establish their advantages over more conventional routes. Therefore, the SSM community must disseminate their findings more effectively to generate increased confidence in SSM processes in the eyes of our industrial leaders. As such, we have embarked on the task to invite the leaders in SSM research to share their findings in a Special Issue dedicated to semi-solid processing of metals and composites. SSM processing takes advantage of both forming and shaping characteristics usually employed for liquid and solid materials. In the absence of shear forces, the semi-solid metal has similar characteristics to solids, i.e., easily transferred and shaped; by applying a defined force, the viscosity is reduced and the material flows like a liquid. These unique dual characteristics have made SSM routes attractive alternatives to conventional casting on an industrial scale. With the intention of taking full advantage of SSM characteristics, it is crucial to understand SSM processing, including topics such as solidification and structural evolution, flow behavior through modelling and rheology, new processes and process control, alloy development, and properties in general. This Special Issue focuses on the recent research and findings in the field with the aim of filling the gap between industry and academia, and to shed light on some of the fundamentals of science and technology of semi-solid processing.

These proceedings of the 12th International Conference on Semi-Solid Processing of Alloys and Composites contain the papers which were presented at the conference, held in Cape Town (South Africa) between the 8th and 11th October 2012. The aim of these international conferences is to provide a forum where the leading researchers, engineers and industrialists in this field can gather in order to share their work and knowledge, and hold lively discussions concerning current fundamental issues in semi-solid metal processing. Volume is indexed by Thomson Reuters CPCI-S (WoS). The contents are divided into 5 distinct sections: Microstructure and Properties; Process Development; Modeling, Simulation and Rheology; Materials Development and Alloy Design and Industrial Applications.
