2 original lesson summaries in this topic collection.
Topic overview
- Aluminium alloys give aircraft high strength-to-weight; Al–Cu for structure, Al–Si and Al–Si–Mg for castings.
- Age hardening: solution treat, quench to a supersaturated solution, then age to form fine precipitates.
- Precipitates block dislocations; over-ageing coarsens them and lowers strength.
- Refrigerated rivets and clad sheet show practical control of ageing and corrosion.
