No course in science or engineering may remain static. Not only does technology advance and scientific understanding
increase, the academic framework undergoes changes. Thus, periodic revisions are desirable in an effort to optimize
the value of a textbook for students who will be tomorrow's engineers.
Developments such as the high-temperature superconductors are exciting, and the scientific data such as that obtained
from tunneling electron microscopes provide new insights. During the last decade, however, the evolving structure
of the academic environment probably has had a more direct impact on introductory materials courses within the
engineering curricula. Whereas academic departments will continue to have specialists in ceramics, in polymers,
as well as to hybrid composites. Likewise, graduate students working with polyblends give cognizance to phase immiscibilities
and to the microstructure/property relationships utilized by ceramists and metallurgists. Particulate processing
is no longer restricted to ceramics, nor are engineering designs using magnets limited to metallic materials.
In view of these changes, the majority of the current generation of instructors can easily extend the topics of
crystals from single-component metals to binary ceramic compounds, and even introduce simple molecular crystals
when they tech an introductory materials course. Likewise, although reaction rates may differ, the same principles
hold for the phase relationships of ceramics and polymers as they do for metals. Today's instructor easily handles
these topics generically for the several types of materials.
The major modification to this edition has been in the attention to the commonality found within the materials
field, in which structures and properties are considered generically for all materials rather than categorically
by material classes--metals, polymers, ceramics, and semiconductors. The three photos present on the cover and
chapters this sixth edition are symbolic of this generic view; each chosen to pictorially demonstrate the connection
between structure, properties, and performance.
Overview:
Chapter 1 remains as an introduction to the topic of materials, since undergraduate students generally relate
to their product without giving thought to the materials within them. Chapter 2 reviews the necessary chemistry
from the students' previous general chemistry courses, but in doing so extends the topics of bonding and atomic
coordination. The topics of Chapters 3, 4, and 5 are common to all materials--crystal structure, disorder in solids,
and phase relationships, respectively. Included for the first time in Chapter 5 are several molecular phase diagrams,
chosen to emphasize immiscibility, which is pertinent to the more recently developed polyblends.
Chapter 6 combines and extends the subject of reaction rates, while Chapter 7 does the same for an introduction
to microstructure. Although the three principal classes of materials have distinct differences with respect to
these two topics, the bases of the differences are instructive to the subject; for example, the crystallization
rates of metallic, silicate, and polymeric materials.
Chapters 8, 9, and 10 focus on the mechanical behavior of solids. In sequence, they consider deformation, strengthening,
and the characteristics of polymers and composites. Chapters 11, 12, and 13 look at the electromagnetic behavior
of solids--conductivity, magnetic, and the dielectric and optical, respectively. These six chapters are written
to give the instructor options regarding the topics to be selected, depending on the available time and curricular
requirements.
The final chapter (14) addresses performance in service, particularly for severe conditions in which corrosion,
fatigue, heat, or radiation may alter the structure and hence the properties of materials.
Pedagogy:
Teaching aids within the text include not only the Summary at the end of each chapter, but also nearly 175
Examples in which a procedure is outlined before the calculations are made. Wherever appropriate, follow-up comments
supplement the calculations. Practice Problems at the end of each chapter offer a trial run for the student, and
answers to these several hundred problems are available at the end of the text. A new end-of-chapter feature is
the inclusion of Test Problems. Of the nearly 400 such problems throughout the book, the majority either are new
to the text or are significantly modified from those in previous editions. More than 400 Terms and Concepts are
defined in a glossary.
