Rapid prototyping (RP) and tooling (RT) technologies have attracted tremendous R&D interests from both academia and industry in the since the 1990s. More recent interests in RP technologies are towards functional applications of the fabricated parts, such as in rapid tooling applications and replacements of damaged components. Many RP processes and materials have been commercialized but are yet to be able to fulfil the functional requirements because of limited mechanical strengths of fabricated parts. This book thus focuses on the fundamental issues of the laser-induced RP materials and processes. The remedies and possible solutions to RP/RT pertaining to materials and processes are included. The highlighted research issues and presented results are not only informative, but should also be very useful for future commercial developments.

Intended as an introduction to the mechanical alloying technique used in developing different materials systems, this work is suitable for undergraduate and post-graduate students, and also for scientists and engineers who wish to gain some understanding of the process. It begins with a brief introduction providing historical background to the development of the mechanical alloying process. There are several different types of ball mills available, some of them specially designed for the 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. The actual mechanical alloying process is considered and, as it is essential to understand the use of processing-control agents, the physical properties of some commonly used agents are listed. There is coverage of the formation of new materials and mechanical alloying of Al, Ti and Mg alloys and their intermetallics, and the formation of composite materials using this technique is also discussed in detail.Several examples of the mechanical alloying of amorphous materials, an important group of engineering materials where mechanical alloying is commonly employed, are given, and there is a look at the characterization of the alloyed powders.

Fractal analysis has rapidly become an important field in materials science and engineering with broad applications to theoretical analysis and quantitative description of microstructures of materials. Fractal methods have thus far shown great potential in engineering applications in quantitative microscopic analysis of materials using commercial microscopes. This book introduces the fundamentals and the basis methods of fractal description of microstructures in combination with digital imaging and computer technologies. Basic concepts are given in the form of mathematical expressions. Detailed algorithms in practical applications are also provided. Fractal measurement, error analysis and fractal description of cluster growth, thin films and surfaces are emphasized in this book. It provides a comprehensive approach to materials characterization by fractal from theory to application and is therefore an essential source of reference for university professors, professional engineers and research students.

The term rapid prototyping (RP) refers to a generic group of emerging technologies that enable very quick fabrication of engineering components primarily targeted for prototyping applications. With RP, very complex three­ dimensional parts or prototypes can be fabricated without the need of costly tooling and machining. This inevitably leads to much shorter design cycle time and lower cost of building a prototype. Its manifold benefits include significant productivity gains, cost saving, and shortened development time to introduce concept models. As such, RP technologies have attracted tremendous R&D interests from both academia and industry in the past decade. Many different processes and materials have been commercialized and used in industry primarily for the fabrication of physical prototypes. More recent interests in RP technologies are towards functional applications of the fabricated parts, such as in rapid tooling applications and replacements of damaged components. Many processes and materials have been commercialized but are yet to be able to fulfill the aforementioned functional requirements because of limited mechanical strengths of the fabricated parts.

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.
