Ti-6Al-4V ANNEALED PLATE

[StressMan2506]

Does anyone have a full (or partial) range stress-strain curve for this material in the thickness band encompassing 16 mm (5/8")? Or, better still, does anyone have the Ramberg-Osgood parameters?

Thanks in anticipation.

Try the following;
Page 5-66, Figure 5.4.1.1.6 (a) in

MIL-HDBK-5H
1 DECEMBER 1998

There is a stress strain graph for this Ti alloy along with the Ramberg-Osgood parameter, n for various temperatures including room temperature.

Thanks, metengr. I have seen the curve you refer to. It is, I believe, for solution-treated, aged material. I am at home now, so I don't have access to HDBK-5/MMPDS. I think the properties differ for the two conditions...

The figure caption at the bottom states "Typical tensile stress strain curves at cryogenic, room and elevated temperatures for annealed Ti-6Al-4V alloy extrusion."

Thanks again, metengr. Is there any significant difference in properties between extrusion and plate for this alloy?

Based on your question in the other forum, I think you need to contact a titanium producer directly, in order to obtain sufficient confidence in the data that you are seeking. TIMET or RTI would be the two companies I recommend contacting, since they both produce plate.

Thanks, TVP. I will check them out.

RMI Titanium is the correct name. RTI is the larger corporate parent.
