INDEX TO IMAGES
(All the images above were modified from those in an earlier edition of the
class textbook: Materials Science and Engineering: An
Introduction,Third Edition, by William D. Callister, Jr., John
Wiley and Sons, 1994.)
- A: Hot working of a steel bar (color plate 2).
- B: Recrystallization of a heavily cold-worked brass sample.
Upper (green) shows the nucleation of new strain-free grains
withincold-worked matrix, and lower (brown) shows fully
recrystallized structure after grain growth has occured. (Figure
7.21, p 169).
- C: The grip section of a mechanical testing machine (p. 106).
- D: Fatigue fracture surface showing fatigue crack advancement
in upper center, with fast ductile fracture in the darker regions
below (figure 8.25, p. 210).
- BACKGROUND: In the background is a schematic stress-strain
diagram showing the definition of Ultimate Tensile Strength as the
onset of mechanical instability (p. 119).
