The process of applying a specified heat over a specified time and cooling in a specified manner changes the physical properties of metal. A metal has been "heat-treated" when such a process has been applied.
Method of adding specific qualities (e.g., hardness) to metals by controlled beating and cooling.
The processes through which armour is hardened through heating. In general, most iron or ferrous armour is hardened either through work hardening (done by hammering) or by heating it to its critical temperature (dependent upon the technique used) and then quenched in water, urine, oil or other more secret substances. Prior to the 14th century, most hardened pieces were worked, planished, from the hammer rather than heat treated. During the 15th century, there is some evidence that the German armourers, particularly in Augsburg, began to use a sophisticated two step method that achieved a superior hardness and a resiliance to brittleness. See especially Theodore Monnich's article in Chornique: The Journal of Chivalry #13.
A process that uses precise heating and tooling of metals in order to optimize internal stresses and spring properties.
Heating and cooling a solid metal or alloy in such a way as to obtain desired conditions or properties. Commonly used as a shop term to denote a thermal treatment to increase strength. Heating for the sole purpose of hot working is excluded from the meaning of this definition.
modification of properties and structure of alloys by specific heating and cooling cycles.
A secondary operation in the metal stamping process in which the strength and hardness of a metal part is increased through controlled cycles of heating and cooling.
Describes heating material to dry, cure, harden or temper it.
A process for treating metals where heating to a specific temperature and cooling at a specific rate changes the properties of the metal.
A thermal processing procedure that involves an engineered plan depicting the time and rate of heating and cooling of metal products to obtain a specific level of mechanical properties.
A high temperature process that hardens the ball by subjecting a metal or alloy to controlled heating and cooling to improve hardness and other properties.
Enhancement of a material by use of heating and cooling rates.
Subjecting metals to heat treatment.
