A while ago a friend of mine bought a 12"x2" cylinder of TI 6-4 for the hilt of his next sword. He spent one day cutting through the cylinder to cut the length he will use for the pommel off. When I was there we started cutting the the guard and grip pieces off (total of 3 parts). In a safety demonstration he wanted to show me and my brother how flamable titanium really is. So he collected the Ti dust from us sawing through it (we got about 1/2" through it and gave up for the day) and well... here is the demonstration.

Low resolution

Not as low (but still low)

LInks don't go anywhere.:(
 
Sorry, I just copied the link from a previous posting somewhere else. I forgot that I moved the files into a subfolder.
Should work now.
 
Works now, thanks Yop.:D

Pretty impressive but Ti isn't the only one that burns with such explosive display.;)
 
Aluminum is pretty hazardus too.

While sawing with a hack saw we had titanium sparks shooting off.

The same guy in the video (that is not me, I am holding the camera) is making his own 4340Mod steel. He has the black sand and all of the other materials (chromium, carbon, magnesium, molybdenum, nickle I think). He plans on seperating the iron from the black sand using thermite. :D

Themite, the most fun (and danger) you can have with coke cans, rusted steel and a micro torch.

FYI thermite burns at 5500 degrees. I think iron melts at 3900.
 
Just about anything, if ground finely enough, burns nicely. Spread it out a bit and things get...interesting. Plug "grain silo explosion" and "fuel air explosive" into your preferred search engine for some fascinating reading. (And some videos to boot.)
 
But the thing with titanium is that it does not need to be ground finely to burn. I think they tried using it for armor on APCs. The Ti plating caught on fire when hit with an RPG. One of the problems with heat and Ti is that it is hard to forge. Howard Clark once tried forge welding it, it ignited and made a mess of the forge. I think it may have burnt throught the forge and made a mess of the concrete floor as well. Grinding it sends sparks that can fracture a concrete floor.

I'm actually a little afraid of my neighbors shop. He has a lathe for polishing wheels that has aluminum and magnesium powder in buckets and piles under it.
 
I over tightened an oil cooler, and broke off the mounting ears on an engine case. My neighbor had a small welding shop in his shed so I asked him if he could weld aluminum. "I'll give it a try." he said. "Bring it on over."

As we stood there, looking at the pile of ashes that used to be the shed, we realized that the case wasn't aluminum. It was magnesium. But at that point it didn't really matter.
