Titanium Alloy strain-hardening exponent?

Titanium Alloy strain-hardening exponent?

(OP)
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.

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.

RE: Titanium Alloy strain-hardening exponent?

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.
