Preface

In this Eighth Edition we have retained the objectives and approaches for teaching

materials science and engineering that were presented in previous editions. The

first, and primary, objective is to present the basic fundamentals on a level appropriate

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 explain

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 sufficient

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 relevance

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.
