| | Why are metals treated further after casting? | | Factors that determine the structure of metals are their composition and the casting process. These may not give the exact properties required so further treatments (mechanical or heat) are sometimes necessary. These treatments modify its microstructure and change its properties so that they are more suitable for its purpose. In this unit, we will look at:
- Cold working
- Annealing
- Hot working
- Quenching
- Tempering
- Alloying
