Forge welding titanium and niobium?

Sorry, I had to run back to work and couldn't elaborate.

I have a couple of sheets of (cp) ti, and a thin sheet of niobium. Anyone know if these are compatible? I can't find much on the topic.

I'd like to try a mokume style stack weld, but I don't want to just throw the material away if I can get some info before I try it. Any special considerations, or can I tie up a stack with some wire?

If you've done it (or just have an idea), will they anodize nicely? I'm fine with anodizing titanium, but have never tried niobium. I'm guessing they require different voltages so that would be good.

Any information at all (opinions, experiences, links or videos) are welcome.
 
Sometimes Bladsmth is so negative !
You could try explosive welding though your neighbors will think you are even more weird !
 
Doh! He said it can't be done in a forge. Now we HAVE TO try. When you try, just remember to keep it completely free of oxygen. I figure that you would need at least a stainless pouch and a press. I figure that hammering would ruin the pouch, thus the need for a press. Wrapping it with wire would be a waste of material. I've got lots of scraps of Ti but no niobium, otherwise I'd give it a shot.
 
The stainless pouch would likely melt before the titanium got up to forge welding temp... not to mention the fact that niobium melting point is is 1400F higher than titanium's melting point which I'm sure would increase the welding temp considerably.

Yeah, I knew that it had to be an oxygen free atmosphere, but wasn't aware of the difference in forging temps.

This looks beyond my pay grade and equipment.

Zaph, I can send the niobium if you want to try? It's paper thin, although I'm not sure that matters. Actually (just thinking out loud), I wonder, considering the high melt point, if the niobium could be used in place of the ss foil?
 
I would go with mete's idea.

Impact welding. Ask your neighbor if you can borrow his garage for an hour or so, then ask him how much insurance he has...


Impact welding: This video reminds me of when mythbusters 'disappeared' a cement truck with anfo.

Wow... Now *that's* what I'm talking about!
 
If you've ever wondered how they get the copper or aluminum onto the bottom of a stainless steel frying pan, that is how they do it.
