HEAT TREATING in its broadest sense, refers to any of the heating and cooling operations that are performed for the purpose of changing the mechanical properties, the metallurgical structure, or the residual stress state of a metal product. When the term is applied
When the term is applied to aluminum alloys, however, its use frequently is restricted to the specific operations employed to increase strength hardness of the precipitation-hardenable wrought cast alloys. Covers all product forms, many curves
Depending on the exact process being used, furnace temperatures can range from 240 to 1000 F. It is important to keep in mind that the heat treating of aluminum is quite different from steel. Annealing Aluminum alloys are subject to work hardening, also

Heat treating processes for aluminum are precision processes. They must be carried out in furnaces properly designed and built to provide the thermal conditions required, and adequay equipped with control instruments to insure the desired continuity and
From International heat treat consultant David Pye, of Pye Metallurgical we have these thoughts about the heat treatment of heat treatment of heat treatable aluminum alloys is a very sensitive and specialized
The strongest aluminum alloys (2xxx, 6xxx and 7xxx) are produced by age hardening. A fine dispersion of precipitates can be formed by appropriate heat treatment. A general model for decomposition is given, followed by details of the precipitation sequences

HEAT TREATING ALUMINUM FOR AEROSPACE APPLICATIONS It is of low weight. Its alloys can be heat treated to relatively high strengths. It is of reasonable cost, and it is easy to bend and machine. Because of these advantages, aluminum is the
The term for aluminum alloys is frequently restricted to the specific operations employed to increase strength and hardness of the precipitation-hardenable wrought and cast alloys. These usually are referred to as the alloys to
Heat treating is used to change the physical properties of different types of metals and alloys in order to form, bend, or shape the material. The process consists of heating the object to a specific temperature, leaving it at that temperature for a while and cooling the metal according to defined process parameters. In this
