Mechanical alloying (or mechanical milling) was invented in the 1970's as a method to develop dispersion-strengthened high temperature alloys with unique properties. With the discovery of formation of amorphous alloys using this technique, it has received new research interest in developing different material systems. Potential applications of this technique have been demonstrated in different areas of materials research. This book is intended as an introduction to mechanical alloying technique used in difference areas. This book contains basic information on the preparation of materials using the mechanical alloying technique. It is useful not only to undergraduate and post-graduate students, but also to scientists and engineers who wish to gain some understanding on the basic process and mechanisms of the process. The book begins with a brief introduction to provide a historical background understanding to the development of the mechanical alloying process. The experimental set-up in the alloying process is important. Currently there are different types of ball mills available. Some of them are specially designed for mechanical alloying process. Since the resultant materials are milling intensity and milling temperature dependent, ball mills should be carefully selected in order to obtain the desired materials and structures. This is discussed in chapter 2. The actual mechanical alloying process is being considered in Chapter 3. As it is essential to understand the use of processing control agents, the physical properties of some commonly used processing control agents are listed.

This book is a detailed introduction to mechanical alloying, offering guidelines on the necessary equipment and facilities needed to carry out the process and giving a fundamental background to the reactions taking place. El-Eskandarany, a leading authority on mechanical alloying, discusses the mechanism of powder consolidations using different powder compaction processes. A new chapter will also be included on thermal, mechanically-induced and electrical discharge-assisted mechanical milling. Fully updated to cover recent developments in the field, this second edition also introduces new and emerging applications for mechanical alloying, including the fabrication of carbon nanotubes, surface protective coating and hydrogen storage technology. El-Eskandarany discusses the latest research into these applications, and provides engineers and scientists with the information they need to implement these developments. The industrial applications of nanocrystalline and metallic glassy powders are presented. The book also contains over 200 tables and graphs to illustrate the milling processes and present the properties and characteristics of the resulting materials. Guides readers through each step of the mechanical alloying process, covering best practice techniques and offering guidelines on the required equipment Tables and graphs are used to explain the stages of the milling processes and provide an understanding of the properties and characteristics of the resulting materials A comprehensive update on the previous edition, including new chapters to cover new applications

Unique in bringing about a solid-state reaction at room temperature, mechanical alloying produces powders and compounds difficult or impossible to obtain by conventional techniques. Immediate and cost-effective industry applications of the resultant advanced materials are in cutting tools and high performance aerospace products such as metal matrix armor and turbine blades. The book is a guided introduction to mechanical alloying, covering material requirements equipment, processing, and engineering properties and characteristics of the milled powders. Chapters 3 and 4 treat the fabrication of nanophase materials and nanophase composite materials. Chapter 8 provides extensive coverage of metallic glass substances. This book is ideal for materials scientists in industry and in research, design, processing, and plant engineers in the cutting tools and aerospace industries as well as senior level students in metallurgical and mechanical materials engineering. The book will especially benefit metallurgists unacquainted with ball milling fabrication.

Offering one of the field's most thorough treatments of material design principles, including a concise overview of fastener design, the Handbook of Mechanical Alloy Design provides an extensive overview of the effects of alloy compositional design on expected mechanical properties. This reference highlights the design elements that must be considered in risk-based metallurgical design and covers alloy design for a broad range of materials, including the increasingly important powder metal and metal matrix alloys. It discusses the design issues associated with carbon, alloy, and tool steels, microalloyed steels, and more. The Handbook of Mechanical Alloy Design is a must-have reference.

Alloying: Understanding the Basics is a comprehensive guide to the influence of alloy additions on mechanical properties, physical properties, corrosion and chemical behavior, and processing and manufacturing characteristics. The coverage considers "alloying" to include any addition of an element or compound that interacts with a base metal to influence properties. Thus, the book addresses the beneficial effects of major alloy additions, inoculants, dopants, grain refiners, and other elements that have been deliberately added to improve performance, as well the detrimental effects of minor elements or residual (tramp) elements included in charge materials or that result from improper melting or refining techniques. The content is presented in a concise, user-friendly format. Numerous figures and tables are provided. The coverage has been weighted to provided the most detailed information on the most industrially important materials.
