Quenching: Heating the metal work-piece to a suitable temperature above "the Austenite Transformation
Temperature" and cooled It rapidly, it will held internal stress so that the Structure of Metal becomes harden
with possessing less elasticity. In most cases after quenching, tempering has to be done to recover elasticity.
Tempering is recommend for venders, and sub-conductors to adjustits structure or to soften and to restore
elasticity. By Heating the Metal Above the Austenite Transformation Temperature, the Structure of Metal is
expanded and shrinks when it cools. |

Precipitation & Age Hardening is another method to harden the Metal work-piece. Not likely to Quenching,
typical temperature for this process is setting lower than it. At the temperature around 500℃ is used to strength
and to hard the metal. This method also can increase elasticity of the metal. This method places less stress
on the work-piece. |

Precipitation treatment of Precipitation Hardening on stainless steel (PH steel) |
The properties of the metal are able to control by choosing the Heat Treatment
methods. For working on machining of the metal, you choose the work-piece
to be soft. After working on machining, we can again make the metal harder. |

Age Hardening of beryllium copper or copper-titanium alloys |
| This treatment makes the metal stronger and harder with holding high elasticity. |
