Engineering Materials 2

A. Metals
1. Metals
the generic metals and alloys; iron-based, copper-based, nickel-based,aluminium-based and titanium-based alloys; design data
2. Metal structures the range of metal structures that can be altered to get different properties: crystal and glass structure, structures of solutions and
compounds, grain and phase boundaries, equilibrium shapes of grains and phases
3. Equilibrium constitution and phase diagrams how mixing elements to make an alloy can change their structure; examples: the lead–tin, copper–nickel and copper–zinc alloy systems
4. Case studies in phase diagrams choosing soft solders; pure silicon for microchips; making bubble-free ice
5. The driving force for structural change the work done during a structural change gives the driving force for the change; examples: solidification, solid-state phase changes, precipitate coarsening, grain growth, recrystallisation; sizes of driving forces
6. Kinetics of structural change: I – diffusive transformations why transformation rates peak – the opposing claims of driving force and thermal activation; why latent heat and diffusion slow transformations down
7. Kinetics of structural change: II – nucleation how new phases nucleate in liquids and solids; why nucleation is helped by solid catalysts; examples: nucleation in plants, vapour trails, bubble chambers and caramel
8. Kinetics of structural change: III – displacive transformations how we can avoid diffusive transformations by rapid cooling; the alternative – displacive (shear) transformations at the speed of sound
9. Case studies in phase transformations artificial rain-making; fine-grained castings; single crystals for semiconductors; amorphous metals
10. The light alloys where they score over steels; how they can be made stronger: solution, age and work hardening; thermal stability
11. Steels: I – carbon steels structures produced by diffusive changes; structures produced by displacive changes (martensite); why quenching and tempering can
transform the strength of steels; the TTT diagram
12. Steels: II – alloy steels adding other elements gives hardenability (ease of martensite formation), solution strengthening, precipitation strengthening, corrosion resistance,and austenitic (f.c.c.) steels
13. Case studies in steels metallurgical detective work after a boiler explosion; welding steels together safely; the case of the broken hammer
14. Production, forming and joining of metalsprocessing routes for metals; casting; plastic working; control of grain size; machining; joining; surface engineering

B. Ceramics and glasses
15. Ceramics and glasses the generic ceramics and glasses: glasses, vitreous ceramics, high-technology ceramics, cements and concretes, natural ceramics (rocks and ice), ceramic composites; design data
16. Structure of ceramics crystalline ceramics; glassy ceramics; ceramic alloys; ceramic micro-structures: pure, vitreous and composite
17. The mechanical properties of ceramics high stiffness and hardness; poor toughness and thermal shock resistance; the excellent creep resistance of refractory ceramics
18. The statistics of brittle fracture and case study how the distribution of flaw sizes gives a dispersion of strength: the Weibull distribution; why the strength falls with time (static fatigue);case study: the design of pressure windows
19. Production, forming and joining of ceramics processing routes for ceramics; making and pressing powders to shape;working glasses; making high-technology ceramics; joining ceramics;applications of high-performance ceramics
20. Special topic: cements and concretes historical background; cement chemistry; setting and hardening of cement; strength of cement and concrete; high-strength cements

C. Polymers and composites
21. Polymers the generic polymers: thermoplastics, thermosets, elastomers, natural
polymers; design data
22. The structure of polymers giant molecules and their architecture; molecular packing: amorphous or crystalline?
23. Mechanical behaviour of polymers how the modulus and strength depend on temperature and time
24. Production, forming and joining of polymers making giant molecules by polymerisation; polymer “alloys”; forming and joining polymers
25. Composites: fibrous, particulate and foamed how adding fibres or particles to polymers can improve their stiffness,strength and toughness; why foams are good for absorbing energy
26. Special topic: wood one of nature’s most successful composite materials

D. Designing with metals, ceramics, polymers and composites
27. Design with materials the design-limiting properties of metals, ceramics, polymers and composites design methodology
28. Case studies in design
1. Designing with metals: conveyor drums for an iron ore terminal
2. Designing with ceramics: ice forces on offshore structures
3. Designing with polymers: a plastic wheel
4. Designing with composites: materials for violin bodies
