solution treat for aluminium below minimum temp by 1.5C
solution treat for aluminium below minimum temp by 1.5C
(OP)
i have an aluminum alloy 1xxx which had a set temperature of 529 +/-4C Solution treat however the load had a temperature of only 523. can i do another solution treatment to reset or do i have to age and then run the whole cycle again i.e. solution treat followed by age?
would this have an effect on properties?

There was no mention of what process spec (if any) was used for this HT procedure. I checked an old copy of MIL-H-6088 and the only wrought materials with a solution HT temp in the range noted were 6951 sheet and 2618 forgings. Section 6.3.3.4 of MIL-H-6088 talks about potential issues when the solution heat treat temp is below the minimum specified. Section 3.6.2 covers re-solution heat treatment, including limits on the number of times re-solution heat treatment is permitted.
Hope that helps.
