Heat Treatment
Heat treatment is done by heating and cooling metals with specific methods in order to obtain the required properties. Properties such as malleability, ductility, corrosion resistance can be obtained by this process. Heat treatment can be done for both ferrous as well as non-ferrous metals.
The common Heat Treatment methods include
- Annealing
- Normalising
- Hardening
- Ageing
- Stress Relieving
- Tempering
- Carburisation
Advantage
- Increases strength and makes the material more ductile or flexible.
- Wear-resistant properties are achieved in metals.
- Stress is relieved thereby making the machining/welding process much easier.
- Brittleness is improved.
- Electrical and magnetic properties are improved.
