CHAPTER 12: STRUCTURE AND
MECHANICAL PROPERTIES OF
CERAMICS
How do ceramics differ from metals?
Ionic crystal structure depends on charge balance, ion size
Vacancies and impurity defects must satisfy charge balance
Few dislocations brittle!

CHAPTER 11: METAL ALLOYS
APPLICATIONS AND PROCESSING
How do we use our knowledge of phase
transformations to strengthen metals?
Phase diagrams, heat treatments, and precipitation hardening

MECHANICAL FAILURE
How do structures fail?
Fracture: crack growth to rupture at a critical load
Fatigue: crack growth due to cycling loads

MECHANICAL PROPERTIES
How do we describe mechanical behavior?
Vocabulary: Stress and strain
Classes of behavior: Elastic vs. plastic
Characteristic quantities: Stiffness, strength, ductility,
toughness
Goal: Lay the ground work for discussi
CHAPTER 5:
DIFFUSION IN SOLIDS
Why study diffusion?
Diffusion plays an important role in
Alloying
Strengthening and heat treatment processes (Ch. 7)
High temperature mechanical behavior (Ch. 8)

CHAPTER 3: CRYSTAL
STRUCTURES
Why discuss crystal structure?
Density depends directly on atomic arrangement
Many properties depend on bond density and angle
(i.e. crystal orientation)
Crystal structure is basis for crystalline defects
