Help me!!!
I need TI-6Al-4V (if it is possible of other titanium alloys too)hardening exponent value!!!!!
I need it for a FEM simulation in Abaqus!!!

Thanks!!!

RE: TI-6Al-4V hardening exponent

From mechanical property data I have seen, I would use n= 0.15, on average, for Ti and Ti-alloys. The strain hardening exponent will vary with strain rate and service temperature, so you are dealing with a moving target under dynamic load applications.

RE: TI-6Al-4V hardening exponent

Annealed?  Solution treated and aged (STA)?  Strained?  It is important to consider the condition of the material.

Hi guy thanks for the information.
My alloys are:
Titanium Ti-6Al-4V (Grade 5), Annealed
Titanium Ti-6Al-4V (Grade 5), STA
Titanium Ti-6Al-4V (Grade 5), STA Bar
Titanium Ti-6Al-4V (Grade 5), Annealed Bar
Titanium Ti-6Al-4V (Grade 5), ELI, Annealed

for all these may I consider n=0.15???

where may I find this information? (for bibliografy)

Thank you very much!!!!!

:)
