Since doing pwder mettalurgy in a can seems to bend a lot of what we have considered "the rules" I have a question along with an opportunity.

I recently came by some powdered metal that started life as 1095, or something very close. An analysis, however, shows that it is 10% titanium.

So, what will be the effect of the Ti on whether or not the can will weld up in the first place, and what effect will it have on the steel otherwise? I plan on giving this a try, probably after Christmas when things settle down a bit. It's just a matter of how much of it I try with.

I realize that the titanium won't really alloy with the steel, it will rather be in suspension, but will it really suspend?

Inquiring minds want to know.

Thanks,

Gene
 
Since titanium is alloyed in some steels, I would give it a try.

Compact the powder as tight as possible and exclude all air. I would guess that weld heats need to be as high as you can get away with.
 
Try it but don't be surprised if it dosen't work. oxidized titainium won't weld. and if the powder has been around for a while then the titanium has most likely oxidized. If the titanium is in a fine enough form then the steel will weld and you may have little points of titanium in it.
 
little specks of Ti in the mix might be neat but i also think that it will be unlikly to work

but i will wish you luck and hope it does cause i like to see new stuff
 
cool just go do it. think of it as a learning experience, a really really cool fun learning experience that has a slim chance of yielding a good billet as a bonus.
 
Is the alloy 10% Ti, or does the powder have a 10% content of Ti powder in it? If the alloy has Ti in it, give it a shot, i could be cool. If it has Ti powder in it, grab a magnet, put it in a plastic bag and run it through the powder. The steel will sick, the Ti won't, and you'll have your materials separated. The plastic bag allows you to pull the magnet out of the bag when you're over your bucket for separated steel and not have a bunch of it stuck to the magnet.

The Ti is powder mixed with the powdered steel. It's 10% by volume, versus chemical comp of the steel. I know the magnet and plastic bag trick, but really am curious as to whether this will work.

I've already made a billet of Ti/copper, but that was through diffusion bonding. I haven't had time to really work it yet and see what the limits are, but that will be fun, too.

I'm 2 1/2 months out of a rotator cuff surgery, so I'm catching up on orders and getting ready for the Rocky Mountain knife show next month. That doesn't leave a lot of play time right now. I have a couple of other projects up my sleeve, but won't get them done until after the first of the year.
