Shot Peening Aermet 100
Shot Peening Aermet 100
(OP)
I work at a facility that makes aerospace test hardware. We have a requirement to make a part from Aermet 100. The part is highly stressed, with a Factor of safety of 3 on UTS. We have been told not to use Vascomax350 as it's too brittle. and have chosen Aermet 100 as an alternate material.
Our customer is asking us to shotpeen the part after final machining. There are no sharp corners on the part, or sharp changes in x-section.
What is the forums experience with shot peening Aermet 100 to increase fatigue life?
Thanks for any help you can give me

If fatigue is a problem I don't think shot peening can hurt.
Here is one article on shoot peening to correct for HT problems.
