Material Heating

The various stages of heat treatment process are…

Heating – Heating the material uniformly. Non-uniform heating causes the formation of non-uniform microstructure resulting in cracks on a surface.

Soaking – Holding the material at a specific temperature for a certain period to achieve desired properties.
Cooling – Cooling the material at a suitable rate. The cooling of material is
done rapidly, slowly, or quenched.

Process Annealing – Cold-worked parts are frequently annealed to improve ductility and minimize the effect of strain hardening. This heat treatment process lets the strain-hardened parts recrystallize completely or partially. Recrystallization depends on heating temperature, socking time periods, and cooling rates. To increase the formability of the material, an annealing process is carried out in between the cold working process which is known as Process Annealing which allows the further cold working of part.

Normalizing is a similar heat treatment process to annealing having heating, socking, and cooling cycles. The only difference is the cooling rate.
Normalizing processes can be performed on alloys like Brass, Nickel-based alloys, Aluminium, Copper, and Iron-based alloys.
