Introduction
Metallurgy is the field of materials science and material engineering that studies the physical and chemical behaviour of metallic elements, their microstructure compounds and their mixtures, which are mostly known as alloy. Metallurgy can be refers as the technology of metals where science is applied to the production of metals, and the engineering of metal components for the uses of products for consumers and manufacturers.

Metals are widely use in industrial, economic growth and most importantly our daily life. Metals can be found in our car (steel), cell phones (gold, tin), computers (mercury, lithium), electrical wires (copper) and soda can (aluminium). But what is the prime factor that really determines the quality of

Many strip form steels are annealed, such as most tool steels and stainless steels. Non-ferrous alloys are annealed too.

There are 3 types of specialized cycles in Annealing: Normalization ( <60°C)
Normalization is an annealing process applied to ferrous alloys to give the material a homogeneous fine grained structure and make it less brittle. It is used on steels of less than 0.4% carbon to metamorphose austenite into ferrite, pearlite and sorbite.
Although normalizing improves mach inability of a component and provides dimensional stability, it also gives harder and stronger steel but lesser ductility as compare to full annealing. Process Annealing (260 - 760°C)
Process annealing, also refer to as subcritical annealing, in-process annealing, or intermediate annealing, usually is applied in softening metals or to restore ductility to product after cold working by heating the metal below the austenite phase. It is a low temperature anneal that is used for material such as ferrous or non-ferrous) that is going to be reworked. This type of anneal will cause re-crystallization and softening of the cold-worked ferrite grains, but usually will not affect the relatively small amounts of cold-worked pearlite.

Full Annealing (340 - 900°C)
This process usually involves heating of the steel to 30-50 degrees C above the critical temperature of steel and maintaining the temperature for a specified period of time, then the material is slowly cool
