Engineering Materials 1

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

A. Price and availability
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? 

B. The elastic moduli
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
C. Yield strength, tensile strength, hardness and ductility
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 
D. Fast fracture, toughness and fatigue where the energy comes from for catastrophic crack growth; the condition for fast fracture; data for toughness and fracture toughness 
13. Fast Fracture and 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? 
E. Creep deformation and fracture
high-temperature behaviour of materials; creep testing and creep curves;
consequences of creep; creep damage and creep fracture
17. Creep 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 
F. Oxidation and corrosion 
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 
G. Friction, abrasion and wear 
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 Final case study 
27. Materials and Energy in Car Design the selection and economics of materials for automobiles
