need help with material choice
(OP)
I'm attempting to design an implant that must spring back. I tried titanium but it bends and will not return to its original form. any help with safe materials that will spring back? or treating?
its a small part .015 thick at the spring area.

RE: need help with material choice
Have you calculated the stress your 'implant' will see?
Have you compared that to the yield stress of relevant grades of titanium?
Have you discussed heat treat processes etc. for the springs with your vendor?

RE: need help with material choice
If it does not spring back, you have loaded it plastically. If you are designing a spring that must deform a large distance elastically, titanium and beryllium copper are just about the best materials you can select.
There are forums for structure, mechanical engineering and for springs. You must have quite a hobby.

I ended up using PEEK instead. springs right back for what I need.
