PH 13-8 Mo with H1050 condition 2

[zerow3]

Hi, I am trying to look for fatigue crack growth data (da/dN-?K data) for the material PH 13-8 Mo stainless steel with H1050 condition. I have looked through MIL-HDBK-5J, but they don’t have the crack growth data. Anybody able to provide or help me to locate the data?

Thanks, I actually got that article. However, I am after something that is more general. The article is only about small-cracks and only explore R ratio of 0.1 and -1. I am trying to find the fatigue data for long cracks with a wide variety of R ratio (preferably high R ratio, such as 0.6-0.9)

Have you checked Aerospace Structural Metals Handbook (ASMH) or Damage Tolerant Design Handbook (DTDH) from CINDAS? Some university libraries have these references. Here is a brief description from CINDAS, which now has an electronic version of ASMH called ASMD:

I have checked the ASMD from CINDAS; it only got data for condition H1000.

Does the Damage Tolerant Design Handbook contain the same data or they are generated by different parties than the ASMD?

I found this article with a very brief summary below. It might be worth a review.....

The conditions that tend to promote this minimal influence include (1) a ... The PH 13-8 Mo stainless steel was aged at 566 °C for 4 h and air cooled (H1050), ... Long crack growth rate curves for 4340 steel and PH 13-8 Mo stainless ...

TVP;
For some reason I can't open the attachment after multiple attempts. It times out. Can you send me a copy?

Here is the crack growth data for 4340 & PH 13-8Mo mentioned by metengr above:

Thanks, they seem to be useful. Do you happen to know where I can find the S-N data for the same material (with condition H1050)?
