JWCL187_fm_i-xxiv.qxd 11/17/09 1:11 PM Page iv Front Cover: Depiction of a unit cell for the inverse spinel crystal structure. Red spheres represent O2⫺ oxygen ions; dark blue and light blue spheres denote Fe2⫹ and Fe3⫹ iron ions, respectively. (As dis- cussed in Chapter 20, some of the magnetic ceramic materials have this inverse spinel crystal structure.) Back Cover: The image on the right shows the ionic packing of a close-packed plane for the inverse spinel crystal structure. The relationship between this close-packed plane and the unit cell is represented by the image on the left; a section has been taken through the unit cell, which exposes this close-packed plane.

The first, and primary, objective is to present the basic fundamentals on a level appro- priate for university/college students who have completed their freshmen calculus, chemistry, and physics courses.
In order to achieve this goal, we have endeavored to use terminology that is familiar to the student who is encountering the discipline of materials science and engineering for the first time, and also to define and ex- plain all unfamiliar terms. The second objective is to present the subject matter in a logical order, from the simple to the more complex. Each chapter builds on the content of previous ones. The third objective, or philosophy, that we strive to maintain throughout the text is that if a topic or concept is worth treating, then it is worth treating in suffi- cient detail and to the extent that students have the opportunity to fully understand it without having to consult other sources; also, in most cases, some practical rele- vance is provided.
Discussions are intended to be clear and concise and to begin at appropriate levels of understanding. The fourth objective is to include features in the book that will expedite the learning process. These learning aids include: • Numerous illustrations, now presented in full color, and photographs to help visualize what is being presented; • Learning objectives, to focus student attention on what they should be getting from each chapter; • “Why Study .” and “Materials of Importance” items that provide relevance to topic discussions; • “Concept Check” questions that test whether or not a student understands the subject matter on a conceptual level; • Key terms and descriptions of key equations highlighted in the margins for quick reference; • End-of-chapter questions and problems designed to progressively develop students’ understanding of concepts and facility with skills; • Answers to selected problems, so that students can check their work; • A glossary, list of symbols, and references to facilitate understanding the subject matter. The fifth objective is to enhance the teaching and learning process by using the newer technologies that are available to most instructors and students of engi- neering today.
• vii JWCL187_fm_i-xxiv.qxd 11/17/09 1:11 PM Page viii viii • Preface FEATURES THAT ARE NEW TO THIS EDITION New/Revised Content Several important changes have been made with this Eighth Edition. One of the most significant is the incorporation of a number of new sections, as well as revisions/ amplifications of other sections. New sections/discussions are as follows: • Diffusion in semiconductors (Section 5. • Flash memory (in Section 18.
• “Biodegradable and Biorenewable Polymers/Plastics” Materials of Importance piece in Chapter 22. Other revisions and additions include the following: • Expanded discussion on nanomaterials (Section 1. • A more comprehensive discussion on the construction of crystallographic directions in hexagonal unit cells—also of conversion from the three-index scheme to four-index (Section 3. • Expanded discussion on titanium alloys (Section 11.
• Revised and enlarged treatment of hardness and hardness testing of ceram- ics (Section 12. • Updated discussion on the process for making sheet glass (in Section 13. • Updates on magnetic storage (hard disk drives and magnetic tapes—Section 20. • Minor updates and revisions in Chapter 22 (“Economic, Environmental, and Societal Issues in Materials Science and Engineering”), especially on recycling.
• Appendix C (“Costs and Relative Costs for Selected Engineering Materials”) has been updated. • End-of chapter summaries have been revised to reflect answers/responses to the extended lists of learning objectives, to better serve students as a study guide. • Summary table of important equations at the end of each chapter. • Summary list of symbols at the end of each chapter.
• New chapter-opener photos and layouts, focusing on applications of materials science to help engage students and motivate a desire to learn more about materials science. • Virtually all Homework problems requiring computations have been refreshed. Processing/Structure/Properties/Performance Correlations One new feature that has been incorporated throughout this new edition is a track- ing of relationships among the processing, structure, properties, and performance components for four different materials: steel alloys, glass-ceramics, polymer fibers, and silicon semiconductors.This concept is outlined in Chapter 1 (Section 1.7), which includes the presentation of a “topic timeline.” This timeline notes those locations (by section) where discussions involving the processing, structure, properties, and performance of each of these four material types are found. These discussions are introduced in the “Why Study?” sections of appropriate chapters, and, in addition, end-of-chapter summaries with relational diagrams are also included.
Finally, for each of the four materials a processing/structure/properties/ JWCL187_fm_i-xxiv.qxd 11/17/09 1:11 PM Page ix Preface • ix performance summary appears at the end of that chapter in which the last item on the topic timeline appears. Discipline-Specific Modules A set of discipline-specific modules appear on the book’s web site (Student Com- panion Site). These modules treat materials science/engineering topics not covered in the print text that are relevant to specific engineering disciplines—mechanical and biomaterials. All Chapters Now In Print Five chapters of the previous edition were in electronic format only (i., not in print).
In this edition, all chapters are in print. Case Studies In prior editions, “Materials Selection and Design Considerations” consisted of a series of case studies that were included as Chapter 22. These case studies will now appear as a library of case studies on the book’s web site (Student Compan- ion Site) at www.com/college/callister.
