Also found in: Dictionary/thesaurus, Medical, Encyclopedia, Wikipedia | 0.03 sec. |
annealingControlled cooling of a material to increase ductility and strength. The process involves first heating a material (usually glass or metal) for a given time at a given temperature, followed by slow cooling. It is a common form of heat treatment. Normalizing is a type of annealing where a metal is heated to a point above its critical temperature before being cooled. This helps to refine the grain. |

For diamonds, annealing had previously been used only to change the mineral's color. The now commonly employed optimisation methods of simulated annealing and evolutionary algorithms (which include genetic algorithms) possess distinct advantages over the Monte-Carlo [2] and grid search [3-4] methods previously employed, in that they search the relevant parameter space in a much more efficient manner. They are said to be ideal for low temperature applications, including annealing, preheating, powder or liquid paint curing. |
