TI-6Al-4V hardening exponent

[leo81]

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!!!

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.

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!!!!!
