How Does Annealing Work?

Answer

Annealing is a process where a material is altered by heat treatment. It works by heating a material to above critical temperature until it glows; maintain it a suitable temperature then cooling it slowly causing changes in its properties such strength and hardness. Annealing is used to soften materials, relive stress, induce ductility and refine the structure of the material

Annealing is a heat treatment process in metallurgy or material science in which a material is altered. It works by creation of special condition above critical temperature thus causing changes in a materials property such as ductility and hardness.
Annealing works to strengthen or soften material like copper and glass by creating a chemical reaction inside a specially-made oven. Each material has a certain temperature that it needs to be during the annealing process.
