Zinc Alloy Fatigue 2

[ottomated]

I'm trying to get reliable information on fatigue performance between different zinc alloys, particularly between Z3 vs Z8.

I've found a really good study on this subject, but they wrote off Z8 results as inaccurate because of the unusually large grain size found in their particular specimen they got.

I know metals with HCP structure don't usually have great fatigue performance, but zinc is really cool.

I'd like to use it but I need to determine what its weaknesses are. Do you all know of a reliable study that has S-N curves on all the zinc-alloys?

I don't have the book in front of me right now, but there is one snippet of data available here:

If you want a reliable component , don't make it out of zinc.

zinc falls between aluminum and steel in my opinion. it's always good to have an option in the middle. it sounds like 50 mpa is the magic number I need to remain within to keep indefinite fatigue resistance.
