ORGANIZATION OF THE TEXT

There are two common approaches for materials science and engineering—one that

we call the “traditional” approach, and the other which most refer to as the “inte-

grated” approach. With the integrated approach, one particular structure, character-

istic, or property for all three material types is presented before moving on to the

discussion of another structure/characteristic/property. This is the order of presenta-

tion in this book,Fundamentals of Materials Science and Engineering, Third Edition,

which is depicted by the following schematic diagram:

Some instructors prefer this organizational approach for the following reasons:

(1) students come to realize and appreciate differences in the characteristics and

properties of the various material types; and (2) when considering properties and

processing, all material types should be included.

With the traditional approach, structures/characteristics/properties of metals are

presented first, followed by analogous discussions for ceramic materials and poly-

mers. Our other book,Materials Science and Engineering: An Introduction, Seventh

Editionis organized in this manner.

NEW TO THIS EDITION

New/Revised Content

Several important changes have been made with this Third Edition. One of the

most significant is the incorporation of a number of new sections, as well as revi-

sions/amplifications of other sections. New sections/discussions are as follows:

• One-Component (or Unary) Phase Diagrams (Section 10.6)


• Compacted graphite iron (in Section 13.2, “Ferrous Alloys”)


• Lost Foam Casting (in Section 14.3, “Casting”)


• Temperature dependence of Frenkel and Schottky defects (in Section 5.3, “Point
  Defects in Ceramics”)


• Crystallization of glass-ceramics, in terms of continuous cooling transformation
  diagrams (in Section 13.5, “Glass-Ceramics”)


• Permeability in polymers (in Section 6.7, “Diffusion in Ionic and Polymeric Ma-
  terials”)
  Those sections that have been revised/amplified include the following:


• Treatments in Chapter 1 (“Introduction”) on the several material types have
  been enlarged to include comparisons of various property values (as bar charts).


• Refined terminology and representations of polymer structures (Sections 4.
  through 4.8).


• Eliminated discussion on fringed-micelle model (found in Section 4.12 of the
  second edition).


• Enhanced discussion on defects in polymers (Section 5.5).
