Preface
Advances in materials science and engineering have had a profound effect on the world's technological development. The present-day globalization of the world's economy is driven by high technology, and the research and development of materials is in the forefront of our changing world society. As a consequence many people can benefit from a study of engineering materials technology. Our first edition was written for students in engineering and industrial technology programs. Since then we have learned that many other people found our text refreshing and useful to them, including professors, secondary school teachers, and industrial trainers with the responsibility to teach materials science and technology subjects.
Because materials technology is so pervasive in our readers' lives, we continually encourage them to become "materials observers" and point out the relevance of this important subject as seen in everyday products and systems. Another effective teaching tool for learning, in evidence since the original text, is the use of integrated common themes: 1) relationships among structure, properties, processing, and applications of materials, 2) the importance of consideration of the total Materials Cycle in material synthesis, selection, processing, and economics, 3) the need for environmentally friendly design and manufacturing of systems and products, 4) new and/or improved technologies that influence many aspects of engineering materials technology such as micro/nanotechnology, recycling, surface engineering, smart materials, intelligent structures, and biomimetrics, 5) encouragement for the reader to explore the many resources and databases outside this book including the use of the Internet, and 6) the role of standard practices in all aspects of design, testing, processing, manufacturing, selection, and applications of materials.
In a rapidly advancing society, people must have a sufficient technical background to understand the basis for those new technologies thrust upon them on nearly a daily basis. But this understanding is only a first step. To make a living using these new technologies will be a necessity. All of us will be called upon to be better users of these technological developments which will require the use of less of the earth's dwindling resources accompanied by a reduction in pollution of the planet earth. Accomplishing these broad objectives calls for not only intelligent citizens but intelligent consumers. Throughout the book we point to efforts to strike a balance between improving materials, processes, products, and systems and those impacts on our environment with approaches such as "green design," "green manufacturing" and "green materials:" Building on the drive for "green design and manufacturing" for a sustainable environment we have included extensive coverage of product and system Life Cycle Analysis as related to the total Materials Cycle.
We have added a number of new features to this edition of the text, such as the EMT WEBLINKS in each module. These links will help students view dramatic images, animations and movies, probe databases, and observe R&D at corporations, universities, and government laboratories. They also permit the learners to explore numerous examples of the rapid advancements in the fields of material sciences and engineering, and in some cases engage in tutorials and other interactive exercises. Also, a color section provides vivid images of a wide array of example materials, which are among the many new graphics that help illustrate concepts.
Knowledge of new, advanced materials in all members of the family of materials is extensive. In addition, problems incurred in actually applying these materials are also brought to the attention of our readers. The span of time and the development efforts expanded on bringing new advance materials to the production phase are described. The development of technologies that will permit these materials to be processed economically in industry and the ever-present need for compromise in applying these new materials to safe and reliable products and structures is examined. The above statements are sufficient justification for more study of the role of processing and fabrication of today's engineering materials. Near-net shaping, rapid solidification, rapid prototyping, thermal spraying, hydroforming, and tailored blanks are but few of such subjects. We also examine materials as found in building construction and civil engineering technologies. Corrosion gets expanded coverage, including electrochemistry principles, methods of corrosion prevention, and better design procedures, due to the recognized fact that all materials are subjected to corrosion under service conditions.
To present the fundamentals of materials science on a level appropriate to learners who have not completed formal courses in chemistry, physics or mathematics beyond the uses of algebra is uppermost in our mind. As a consequence the terminology is defined while using a maximum of graphics such as equations, graphs, tables, and micrographs. Illustrative problems requiring calculations are numerous whenever a law or principle can be expressed as an equation. Emphasis is consistently placed on the proper use of units in solving equations using both the English and International System (SI) of units. Substitution of units as well as numbers in equations is stressed as being essential for arriving at a correct answer. Problems in materials science, in general, require a degree of creative analysis of concepts coupled with research into databases in order to solve them. Ample opportunity for this type of problem-solving endeavor is provided by problems contained in each module's Self Assessment section. Many of these types of questions can serve as useful class discussions. ORGANIZATION
The book is organized in self-contained modules that consist of:
Module Outcomes that present what the reader should be able to do after studying the module; Pause & Ponders that present case studies or applications of materials developments, aimed at sparking the reader's interest and providing a reason to learn the content; Solved problems and numerous illustrations and examples representing a full range of products, systems, and technologies that support concepts within the module's topic; Applications & Alternatives that reinforce the concepts learned by illustrating current use of the information; Self-Assessments that provide open-ended essay questions, problems to solve, and objective questions; References & Related Readings that provide source information, plus a listing of useful handbooks, journals, periodicals, and similar data; and Listings of Experiments and Updates from past National Educators Workshops, which can be obtained by using information in the Instructor's Manual.
The experiments and demonstrations listed in each module have been tested and thoroughly peer-reviewed and offer some excellent activities to supplement the text. The answers to all the problems and questions for the Self-Assessments are available in the Instructor's Manual, which offers a test bank from the Self-Assessments and other useful supplements.
The book's organization—including numerous tables in modules, and extensive appendices, coupled with key terms highlighted in bold face—make it comprehensive enough to serve as a Ready Reference Book on materials for the immediate future and beyond.
Please become familiar with the Contents and Index section. We have taken great care to fully develop these features in order to help you make the many cross-references required of this wide-ranging discipline of engineering materials technology. With the Contents you can locate many useful aids in the Appendix such as Greek symbols, S1/US Customary conventions and conversions, tables of properties, ASTM abbreviations, hardness to strength conversions, trade names, material selection guides, and more. Within modules you will find useful visual aids such as our hardness scale comparison figure. All of these features are cross-referenced in the Index. This book should be a useful guide or ready reference, much like Machinery's Handbook, which you should keep at your side as you engage in engineering/industrial problem solving. NEW: UPDATES AND OTHER RESOURCES
As creator of the National Educators Workshop series (NEW: Update) in 1986, Jim Jacobs has co-directed these annual workshops which aimed at providing emerging concepts on engineering materials, science, and technology with emphasis on laboratory experiments. Major sponsors of these workshops and related research were the National Aeronautics and Space Administration (NASA), National Institute of Standards and Technology (NIST), and Department of Energy (DOE). Faculty from community colleges, four-year colleges, and major universities from across the United States, Canada, and other nations gathered at these sessions to share ideas on more effective materials education. Many of the leading corporate and governmental agencies with materials science and engineering laboratories prov
