Engineering Materials
2 original lesson summaries in this topic collection.
Topic overview
- Blocking dislocations strengthens metals; cold work does this but lowers ductility.
- Annealing recrystallises grains to restore ductility; normalising refines grains by air cooling.
- Quenching forms hard, brittle martensite; tempering adds toughness.
- Alloys (carbon steel, stainless, brass, bronze, solder, aluminium alloys) tailor properties.
