Hi,

New to this group and figured I would post a question.

Wondering if there are any metallurgist's on this group, or someone who
knows how to heat treat aluminum?

What I've got is 2024 in a "O" rating and would like to heat treat it
to at least a T3, if not higher. Thickness's I am working with are .032
/ .063 /.080.

I know there is a way to do this with an oven and heat. I have access
to an oven that is programable and could melt aluminum. It is also
programable to step down in stages, for desired times and temps.
Anyone know how to do this?

Thanks, Matt

I'm not a metalurgist, but have hammered out parts in O condition
and taken them to a local heat treat outfit (they have the quality
control / skills to do it right the 1st time, etc.) plus they will
keep my parts on ice for me in W condition so I can straighten
them before they get to final temper (T-42).

Solution & precipitation heat treatment for 2024:

Temperature = 910-930 Deg. F


Soaking Period (Minutes)

Minimum Maximum (Clad only)
-------------------------------------|-------------------
Material Salt Air | Salt Air
Thickness: Bath Furnace | Bath Furnace
-------------------------------------|-------------------
..010 - .012 10 10 | 15 15
..013 - .016 10 20 | 15 25
..017 - .020 10 20 | 20 30
..021 - .032 15 25 | 25 35
..033 - .063 20 30 | 30 40
..064 - .090 25 35 | 35 45
..091 - .125 30 40 | 40 50
..126 - .250 35 50 | 45 60
..251 - .500 45 65 | 55 75

* Over .500 inch: Add 20 minutes per additional 1/2 inch
or fraction thereof in salt, 30 minutes per additional 1/2
inch or fraction thereof in air.

Initial temper = 2024-W
Precipitation Treatment = Room temperature
Final temper = 2024-T4 / T42 (after 96 hours)

-----------------------------------------------------------

Limits for quenching in glycol / water solutions:

Maximum nominal Concentration of Glycol Quenchant
material thickness: (percent by volume)

Type I | Type II
----------|-------------
.040 34 max | 34 max
.063 28 max | 22 max
.071 22 max | n/a
.080 16 max | 16 max

If you haven't already, I suggest you post this in

Just download MIL-H-6088 from the public STINET site.

All the information you could ever need is in there.

No point in reproducing it here.
