Titanium Alloy strain-hardening exponent? 1

[Jabberwocky]

Can anybody point me towards a source for the strain-hardening exponent for Titanium? Specifically Ti 6Al 4V ELI, annealed. I've seen people give numbers around n=0.15, but I need an actual source to cite.

Thanks in advance.

The strain hardening exponent, n, is provided in the link below. Review Chapter 5, 5.4, Figure 5.4.1.1.6(b) annealed Ti-6Al-4V. At RT, n looks to be 0.21

Thanks! I found that handbook but got distracted by the switch to MMPDS-01 and then, admittedly, I was looking for a tabular format and not paying enough attention to the graphs.

Watch the orientation. If the original part has and preferred grain orientation to it then each direction will have a different factor. This is usually only an issue with sheet product.
