To heat metal, glass or other materials above the critical or re-crystallization temperature, then cool, to eliminate the effects of color working, relieve internal stresses or improve electrical, magnetic or other properties
A process, consisting of heating to and holding at a suitable temperature followed by cooling at a suitable rate, used primarily to soften metallic materials, such as steel This process also simultaneously produces desired changes in microstructure, as in other properties, such as improvement of mechanical or electrical properties, increase in stability in dimensions, facilitation of cold work, etc Also see Continuous Anneal and Batch Anneal
To soften & relieve strains in any solid material, such as metal or glass, by heating to just below its melting point & then slowly cooling it Annealing generally lowers the tensile strength of the material, while improving its flex life & flexibility
-The process of controlled heating and cooling of a metal In wire and cable products, copper and aluminum are annealed to increase flexibility while maintaining adequate strength
To soften and relieve strains in any solid material, such as metal or glass, by heating to just below its melting point and then slowly cooling it This also generally lowers the tensile strength of the material, while improving its flex life
To soften metal by heating and slowly cooling In annealing cast iron the carbon is burned out, near the surface, leaving the outer surface tough and strong while the interior is hard
To soften and relieve strains in any solid material, such as metal or glass, by heating to just below its melting point and then slowly cooling it Annealing generally lowers the tensile strength of the material, while improving its flex life and flexibility
To subject a material to a heat treatment to remove the effects of cold work, lowering its tensile strength, rendering it softer with greater elongation
A means of tempering a hand-made glass marble to reduce its brittle nature and give it added strength Once completed, the marble is placed in an annealing oven where its temperature is reduced slowly over a 24 hour period to room temperature The removal of differential thermal stress Machine-made glass marbles are not annealed
The process of softening metal For ferrous metals, that is those containing iron, the process involves heating the steel up to its critcal temperature and then slowly cooling it For non-ferrous metals such as brass, bronze, silver, gold, aluminum and the like, the process is exactly opposite The metal is heated to the critical temperature and then quickly quenched in water, snow, urine, or oil What annealing actually does on a molecular level is to allow the metal crystals to realign, moving them into their more relaxed state When the metal is worked, the crystals are moved out of alignment, contributing to both hardness and brittleness Practically, in the production of arms and armour the metal must be annealed as it is worked, otherwise the metal might stress enough that it will crack
- A process that prevents or removes strain by heating glass above a certain temperature and then cooling slowly in a very controlled manner Used in glass manufacturing
To subject to great heat, and then cool slowly, as glass, cast iron, steel, or other metal, for the purpose of rendering it less brittle; to temper; to toughen
