What does this have to do with the failure? Nothing!!!! 7449 alloy has failed in the desigh spec.. This is fact. I want to hear what the resolution is.
There is some ambiguity in my mind relative to your proclamation. Do you mean:
a. The 7449 alloy was either off chemistry or improperly processed during subsequent heat treatments?
or,
b. The rib structure made from the alloy was marginally designed to the point the capability of the alloy was exceeded by stress levels being experienced in service?
Please clarify if you would, thanks,
