4330 vs 4330V vs 4330V mod
(OP)
I'm looking for information comparing the various 4330-type alloys (V, V mod, V mod+Si) focusing on fatigue resistance (minimum crack propagation rate) and fracture toughness. I've found very little information comparing the alloys. Any help is appreciated.

I would recommend you either attempt to locate a copy of the Aerospace Structural Metals Handbook on Ferrous alloys (FeUH) in a university library or through looking around the Internet. The thread below is where I obtained one of the excellent excerpts that dealt with 4330V and the explanation for modified 4330V.

I appreciate the guidance; I have a copy of that handbook. I'm hoping for more quantitative data comparing the different alloys.
