effect of delay between solution heat treat and artificial aging
effect of delay between solution heat treat and artificial aging
(OP)
Is it possible to overage (and weaken) 7075 forged material if there is a significant (eg: 2-3 months) delay between solution heat treatment/quench, and artificial aging to T6 condition? AMS 2770J table 7 note 5 indicates that furnace aging can be started any time after quenching, which suggests there is no delay limit.

So the next question is why is there no time limit between quench and artificial aging in AMS 2770 (or MIL-H-6088). Is there a risk of overaging so that the mechanical properties do not meet 7075-T6 as listed in MMPDS?
