I am having no luck finding temperature reduction factors for 7075-T73. MMPDS has them for T6 only.
Another question is if I have 7075-T73 and it will see a maximum exposure of 250F for a cumulative long time will it keep losing its strength, permanently? I see to get T73 temper, after solution heat treat, you first heat to 225F for 6-8hrs, than heat to 335 for 6-8hrs.
Thank you
