Fatigue material data for Titanium Alloy (Ti-6AI-4V)

Fatigue material data for Titanium Alloy (Ti-6AI-4V)

Fatigue material data for Titanium Alloy (Ti-6AI-4V)

(OP)
I'm doing a fatigue stress analysis of an assembly made of Titanium Alloy (Ti-6AI-4V). So could anyone tell me, please, where I could find the stress-life data (Alternating Stress VS Life) for this material and thank you in advance.
 
I would be so grateful for any information you could share with me.
 

RE: Fatigue material data for Titanium Alloy (Ti-6AI-4V)

Not exactly a composite...you might do better to red flag this post and ask the moderators to remove it, then re-post in a metallic forum.

However, MIL-HDBK-5 has a fair bit of S-N data for Ti-6-4.

I have half a memory that there's a special high-purity grade for biological purposes. The fatigue might be a bit different for that.

The following links are from a post a few months old, so they might have changed.

Several choices for the last version of MIL-HDBK-5 (MIL-HDBK-5J):

You should also find data in the Atlas of Fatigue Curves from ASM ($200+).

RPstress, thank you a lot for your help. I'll take a look at all the links that you have provided.
 

RE: Fatigue material data for Titanium Alloy (Ti-6AI-4V)

(OP)
I found the best-fit S/N curve for Ti-6AI-4V (in MIL-HDBK-5H) but I can't extract the points. Is it possible to get the fatigue material data stored as tabular alternating stress vs. life points?

I may repost the question in a metallic forum but the information that you have provided is very useful, that's why I hope getting another useful one.

Thank you for any further information
 

RE: Fatigue material data for Titanium Alloy (Ti-6AI-4V)

If you have access to the http://www.Knovel.com/ reference system you will find that they have digitised most of the MIL-HDBK-5J graphs. You might get a free trial period...they might want a local rep to visit you before they do so.

On the other hand these graphs have been used as hard copy for decades. No reason why you shouldn't digitise them yourself in or print them and read them carefully by eye.

(OP)
Really, I can't find the words to thank you for your valuable help. Although it was not exactly a composite, but the answer was the most accurate that I can obtain.

Chapeau, RPstress.

Best reagrds,
Shaban
