Heat Treatments

Heat Treatments are usually used in manufacturing of mechanical components; these metalworking processes provide an efficient way to alter the specific composition of alloys by controlling the rate just below their critical casting temperature from heating upon cooling, enhancing specific mechanical properties as: hardness, stress-strength, toughness and high ductility.

Basic steps involved in a good heat treating process are: heating phase, by heating the machined component throughout in order to prevent the temperature differences which cause alteration and consequent grains. 

Holding temperature:  heat treating requires precise control over temperature, time held at a certain temperature and cooling rate depending on unit-size, material and mechanical properties wanted to be enhanced.

Cooling a metal will usually suppress the precipitation to a much lower temperature, the transformation may be suppressed for hundreds of degrees below the lower critical temperature so that the structure may change from one chemical composition to another, it may stay the same, or it may revert to its original form depending on the type of metal and the rate of cooling: all of these changes are predictable; for that reason, many metals can be made to conform to specific mechanical structures.
