The main difference between full annealing and normalizing is that fully annealed parts are uniform in softness (and machinablilty) throughout the entire part; since the entire part is exposed to the controlled furnace cooling. In the case of the normalized part, depending on the part geometry, the cooling is non-uniform resulting in non-uniform material properties across the part. This may not be desirable if further machining is desired, since it makes the machining job somewhat unpredictable. In such a case it is better to do full annealing.
spherodizing, normalizing, full annealing, process annealing, and stress relief
can we reduce the heat treatment time in carbon steel through normalizing instead of annealing?
In annealing you heat the material to a very high temperature (In case of Steel above the upper transformation temperature), hold it and then slowly cool it in the furnace atmosphere itself. This makes the grain size coarse. Contrary to this, in normalizing you heat the ferrous material (as it is only applicable to ferrous materials) and remove it from furnace and let it cool in the air. So the material becomes hard. The reason for this being you get a much refined fine grain structure.
Annealing temperature is the temperature at which a material is heated to relieve internal stresses and increase its ductility, while melting temperature is the temperature at which a material transitions from a solid to a liquid state.
Normalizing Is a heat treatment process (predominantly used on Steels) It makes the material softer but does not produce the uniform material properties of annealing. A material is normalized by heating it to a specific temperature and then letting the material cool to room temperature outside of the oven. This refines the grain size and improves the uniformity of microstructure and properties of hot rolled steel. Normalizing is used in some in the production of large forgings such as: railroad wheels and axles and on some bar products. The process is less expensive than annealing.

Sintering is a process of compacting and forming a solid mass of material using heat without reaching its melting point, while annealing is a heat treatment process that involves heating a material to a specific temperature and then slowly cooling it to relieve internal stresses and increase ductility. Sintering is used to form objects, while annealing is used to improve a material's properties.
water should be used for narrow parts like sheet or else high amount of residual stresses are made in the part.
annealing for steels
The annealing temperature is the temperature at which a polymer is heated to relieve internal stresses and improve its properties, without melting it. The melting temperature is the temperature at which a polymer transitions from a solid to a liquid state. In polymer processing, annealing temperature is used to improve the polymer's structure, while melting temperature is when the polymer becomes a liquid for shaping.
The recommended annealing temperature for C145 copper is typically between 600-750°C (1112-1382°F). It is important to follow specific guidelines or recommendations provided by the material supplier or manufacturer for the best results.
