Welded CVN properties of 5456 aluminum
Welded CVN properties of 5456 aluminum
(OP)
I'm looking for a good reference which would give me properties of 5456 H321 or H116 aluminum in 1/4-1/2" plate, as welded with a 5556 wire.
I've found allowable values in the ABS handbook, which gives yield, tensile and shear strength, but I'm missing any kind of charpy v-notch toughness information. I've tried AWS 1.2 and 2.1, as well as a weld wire manufacturer, but while they were helpful in their way, they didn't have what I needed.
We're going to be qualifying a weld proceedure, eventually, but I'd really appreciate a place to start.
If anyone's familiar with a good text, reference or code, I'd love to know.
Thanks!

So, CVN impact testing is really not going to provide much in the way of fracture toughness behavior. There are no correlations for CVN to KIc for aluminum alloys. There are published values for toughness properties, and this is what should be investigated, if anything.

I should have mentioned a bit more about the context.
Strain rate is very important for the load case I'm considering, at least as far as the steel components are concerned. Everything's basically over in less than 50 ms in a ~40Hz system, and the primary load pulse is 15ms or so.
It doesn't seem like this would be unimportant.

Has anyone seen anything like that in a requirement or code before?
Thanks again
