Intercritical annealing is where the metal is heated to between its lower and upper critical temperature point to allow partial transformation of the matrix into austenite followed by slow cooling or holding below the lower critical temperature point.
Reducing stress in the steel.
It's heat treatment. By heating and cooling a metal under very controlled circumstances the properties of the metal can be improved.
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.
because it removes the tempering(hardness) of the object, generally on the surface, and makes it easier to work the metal without ruining your tools or "work" hardening the surface.
This process was originaly developed to enable relay and solenoid components to be made from low cost steels. This process reduces carbon and nitrogen levels in the steel resulting in parts having high permeability, low magnetic aging, large ferrite grain size and bright finish.
annealing for steels
spherodizing, normalizing, full annealing, process annealing, and stress relief
Annealing and Sintering are the same processes.
Annealing is making something stronger or more resolute. An example sentence would be: The annealing has to be done before it's complete.
The annealing temperature for this alloy is between 800 and 1200 F.
Annealing is the heat treatment given to a semiconductor material. Annealing is the process by which the lattice damages are repaired. The damages are generally done by ion implantation on semiconductor material.
annealing means the process of heating a metal to increase its softness and reduce its brittle nature.
Annealing. Heat from 1010oC to 1120oC and cool rapidly in air or water. The best corrosion resistance is obtained when the final annealing is above 1070oC and cooling is rapid.
There are three stages in the annealing process. The first stage is when a metal is heated up and it is called the recovery stage. The second stage is called recrystallization and the third stage is called gain growth. Each stage represents a higher temperature in the annealing process.

Figure it out GEEK!
can we reduce the heat treatment time in carbon steel through normalizing instead of annealing?
