Water is the most commonly used quenchant, and typically the most effective quenchant for aluminum alloys. Any forming that needs to be done to a solution heat treated part should be done very soon after quenching is complete.
What is T6 heat treatment process?
The T6 thermal cycle consists of a solution heat treatment followed by a water quenching and then an age hardening (or precipitation hardening). The solution heat treatment leads to the dissolution of intermetallic phases and the spheroidization of eutectic Si with a resulting improvement of alloy ductility [9,10].

What is solution heat treatment in aluminium?
Solution treatment involves heating the aluminum to a temperature of 430-540°C (800-1000°F), at which alloying constituents are taken into solution (i.e., brought near their melting point) prior to a rapid quench.
Does aluminum need to be heat treated?
Conclusion. While not all aluminum alloys benefit from heat treatment, we can heat-treat several alloys to increase the ease of forming or the strength of the finished product. Unlike steel or iron, aluminum requires rigid heat control to achieve optimal results, so special equipment is often required.

Tempering treatment process
This treatment is a two-step process, the first being the heating of the solution and the second the action of aging. During the first step, the alloy piece is submerged in a solution that has a steady temperature of 980 °F (527 °C). The piece stays in the solution for an hour before it is submerged in cold water.

What temperature does aluminum have to be to be a T4 temper?
This is called the T4 temper. If we take this material and heat treat it at a temperature between 325 and 400 degrees F, the alloying elements begin to form ordered arrays of atoms in the aluminum matrix. These arrays are called GP zones, and they strengthen the aluminum considerably.
What is GP zone?
These arrays are called GP zones, and they strengthen the aluminum considerably. This heat treatment is called aging, which results in material with a T6 temper. Three commonly used time/temperature cycles are used for aging—one hour at 400 degrees F; five hours at 350 degrees F; and eight hours at 325 degrees F. All are equally effective.
Is 6061 T6 a mechanical straightener?
There is no doubt that the result will be 6061-T6 properties if you do it properly. The main difficulty is that the component usually distorts quite a bit during quenching and requires significant mechanical straightening before aging. This is often very difficult or even impossible, especially on large weldments.
Is aluminum T4 or T3?
To be considered T4, the aluminum plate (or extrusion, etc.) must be produced, allowed to cool, and then solution treated and quenched. However, aluminum producers quench extrusions right out of the extrusion press while they are still hot. Technically, this produces T3 material, not T4.
