1. Engineering Materials and their Properties
Examples of structures and devices showing how we select the right material for the job.

2. The Price and Availability of Materials
What governs the prices of engineering materials, how long will supplies last, and how can we make the most of the resources that we have?

3. The Elastic Moduli
Stress and strain; Hooke’s Law; measuring Young’s modulus; data for design

4. Bonding Between Atoms
The types of bonds that hold materials together; why some bonds are stiff and others floppy

5. Packing of Atoms in Solids
How atoms are packed in crystals - crystal structures, plane (Miller) indices, direction indices; how atoms are packed in polymers, ceramics and glasses

6. The Physical Basis of Young’s Modulus
How the modulus is governed by bond stiffness and atomic packing; the glass transition temperature in rubbers; designing stiff materials -man-made composites

7. Case Studies of Modulus-limited Design 
The mirror for a big telescope; a stiff beam of minimum weight; a stiff beam of minimum cost

8. The Yield Strength, Tensile Strength, Hardness and Ductility
Definitions, stress-strain curves (true and nominal), testing methods, data

9. Dislocations and Yielding in Crystals
The ideal strength; dislocations (screw and edge) and how they move to give plastic flow

10. Strengthening Methods and Plasticity of Polycrystals
Solid solution hardening; precipitate and dispersion strengthening; work-hardening; yield in polycrystals

11. Continuum Aspects of Plastic Flow
The shear yield strength; plastic instability; the formability of metals and polymers

12. Case Studies in Yield-limited Design
Materials for springs; a pressure vessel of minimum weight; a pressure vessel of minimum cost; how metals are rolled into sheet

13. Fast Fracture and Toughness
Where the energy comes from for catastrophic crack growth; the condition for fast fracture; data for toughness and fracture toughness

14. Micromechanisms of Fast Fracture
Ductile tearing, cleavage; composites, alloys - and why structures are more likely to fail in the winter

15. Fatigue Failure
Fatigue testing, Basquin’s Law, Coffin-Manson Law; crack growth rates for pre-cracked materials; mechanisms of fatigue

16. Case Studies in Fast Fracture and Fatigue Failure
Fast fracture of an ammonia tank; how to stop a pressure vessel blowing up; is cracked cast iron safe?

17. Creep and Creep Fracture
High-temperature behaviour of materials; creep testing and creep curves; consequences of creep; creep damage and creep fracture

18. Kinetic Theory of Diffusion
Arrhenius's Law; Fick's first law derived from statistical mechanics of thermally activated atoms; how diffusion takes place in solids

19. Mechanisms of Creep, and Creep-resistant Materials
Metals and ceramics - dislocation creep, diffusion creep; creep in polymers; designing creep-resistant materials

20. The Turbine Blade - A Case Study in Creep-limited Design
Requirements of a turbine-blade material; nickel-based super-alloys, blade cooling; a new generation of materials? - Metal-matrix composites, ceramics, cost effectiveness

21. Oxidation of Materials
The driving force for oxidation; rates of oxidation, mechanisms of oxidation; data

22. Case Studies in Dry Oxidation
Making stainless alloys; protecting turbine blades

23. Wet Corrosion of Materials
Voltages as driving forces; rates of corrosion; why selective attack is especially dangerous

24. Case Studies in Wet Corrosion
How to protect an underground pipeline; materials for a light-weight factory roof; how to make motor-car exhausts last longer

25. Friction and Wear
Surfaces in contact; how the laws of friction are explained by the asperity-contact model; coefficients of friction; lubrication; the adhesive and abrasive wear of materials 

26. Case Studies in Friction and Wear
the design of a journal bearing; materials for skis and sledge runners; 'non-skid' tyres

27. Materials and Energy in Car Design
The selection and economics of materials for automobiles
