an electric forge with a graphite crucible filled with argon would probably work. since argon is heaver than air it would get all the oxygen out of the chamber
First, we're going to make a glove box. Don't use the grinder. The last thing on that video will be "I found out if I use more material, it takes less heat to get it to temperature... If I make a billet of about 25kg, it should heat itself up. The purity must be good because it said it was weapons-grade"
Its not tooo hard to get your hands on some depleted uranium. But uranium metal has a slight tendency to catch on fire and to produce cancerous dust+smoke
I have to be honest I’ve never thought of forge welding niobium. The reason for that being I’ve never heard of niobium. I'm a true novice! This channel is entertaining, educational and phenomenally under subscribed. There are a couple of 'smithing channels I enjoy but none as much as this one.
Wow Tim that's a pretty amazing video to see. Keep up the great craftsmanship and hard work my friend. Love ur videos. It's always interesting to see because every single video you always seem to try something new. It's very cool to see you test ur skills in every single time u light the forge up. So cool. forge on

Also as a glass blower I have to warn you to wear a welding shade type glasses when exposed to that level of brightness. Cheerio Timothy, your quest for exotic metal knowledge is noble and brave even in forge welding defeat.
Such a cool project Tim! I really love watching your videos and love learning about these cool rare metals through your channel! I'd love to see you anodise it for a project!
@Timothy Dyke how about induction heating of a sealed assembly, like the second assy? induction heat doesn't have an upper temperature, and you could put this inside a glass tube with argon inside.
Niobium is by far my favorite metal to make jewelry from! Relatively easy to work with and anodizes to such amazing colors. Although Tantalum makes the best anodized color of all the reactive metals.
Don't feel bad. I'd rather see you risk it. Success or failure in the project is irrelevant. I think most will agree that I want to see both. Challenge yourself just take us along for the ride.
@17:22 Maybe put it in a vacuum chamber with an infusion of argon gas? Try to cold weld it somehow? Either way this project was an awesome experiment for science! 👍🏾
A bit of an expensive project: 1) build a vacuum chamber with ports for an induction heater 2) form your billet 3) place the billet inside the induction coil, then clamp the billet in a large C-clamp (probably need a ceramic block on either side of the billet, the C-clamp needs to be large enough that it stays pretty far away from the induction coil) 4) Pull a vacuum, you need a high vacuum 10^-3 Torr at most, 10^-6 Torr would be better. 5) Heat with the induction heater (you'll need a strong power source considering how hot it needs to be, and a low frequency inducer to get deep penetration). 6) Leave it for several hours at just below its melting point - being under pressure from the clamp will cause crystals to grow across the interface between the layers. An alternative to an induction heater, microwave heating is also possible. BTW: unless you are using electronics grade (99.9999+% purity, denoted as grade 6.0N, 6.5N, etc.) argon, the argon has too much oxygen for what you are trying to do.
It’s used a lot organic chemical refining. There’s a lot of niobium in the furnace tubes that hydrocarbons are cracked in due to the extreme amount of heat energy required to crack the hydrocarbons chains it’s an ideal metal for this process some of the furnace tubes will run for continuous for months with metal temperatures over 2000 f and an international chemical temperature of close to 1600 f. It’s a very resilient material in extreme temperatures.
Cannot recall the exact temperatures involved, it was a long time ago (during the 80's). But all the Niobium I worked on, hot rolled bar, was rolled well under 850C (1562F). Preheating in an electric furnace, minimum times as Niobium oxidises heavily above about 500C (932F). At high temperatures, it can also easily take in Carbon (from the coke) forming brittle carbides.
A couple ideas... more one idea, and a theory. Perhaps using a press to hold pressure instead of impact welding would allow them to bond. With the weld temperatures needed for the material. If the thermal properties of the tig material isn't high enough, you will likely be melting off the sealing welds of the canister which would allow it to flood with oxidizers. Over all, a good experiment. I always enjoy your content.
First time watching I will subscribe and what I’ve noticed you should get yourself a pair of prescription sunglasses because man that damn thing was hot great video very informative keep up the good work and most of all stay safe
Not sure if I saw this, when tig welding the billet maybe try doing it in an argon bath. Since the tig doesn’t need anything but the current you could flood a box and remove all oxygen. Possibly do your surfacing in that too so there’s zero opportunity for oxidation while closing the billet. In addition I like what others are saying with the argon bath and induction forging.
Trying doing it the Japanese way, with the paper, clay and cloth! And I was reading that you shouldn't keep niobium at a high temp for too long... Maybe more research is required before retesting.
I'm not sure if they get hot enough but from what I understand the Paragon heat treating furnace has an oxygen free chamber once it's heating up. If so that could give you the results you're looking for. Just a thought. 👍⚒
Why has this channel never been suggested to me before all I watch is forging and metal work and I get suggested steak in toaster and other crap hahah deffo earned a sub
The first thing that i would recommend to try to improve the result is the use of safety glasses that are adequate for the job: some heavily tinted glasses, or even a welding helmet. If you can't see what you are doing, it's hard to know what you are really doing. Which brings me to my second point, I don't think it was hot enough. The fact that it's so hot that it blinds you doesn't mean that it is really hot for the niobium, and stops you from seeing the real variations of the color/ light. Third: why didn't you use any flux ? Yes you can forge weld steel without flux, but you will still use it to help reduce the amount of oxydation and improve your chances of success. The use of argon was a pretty interesting idea, as well as trying to forge weld niobium. I am looking forward to see a part 2 of this new quest if you find any information that you think could work!
My only suggestion here if ever you get some more of that material would be to do the set up the same but use some oxy's with four burners and set to carburising flames to heat it. It will get it hotter than your charcoal fire which I think is what's preventing that from fusing. Great video all the same.
Tim my family and I have been enjoying the content you are producing for some time now. thank you for your hard work. With regards to using flux. Is there a flux recipe that can withstand those temperatures? Keep up the hard work. Thank you for the effort we truly enjoy the content you produce.
You may want to try doing a sintering weld of the sheets at a lower, it looks like the sintering temperature is substantially lower for niobium. That would also allow you to have the enclosure be a different metal that is more robust against against oxidizing at your working temp?
Tim.Looks like the heat was to cold a electric furnace and Argon and bring it up to near melting point and use the power hammer process good start Tim.
That looks like a bit of study is needed to understand the techniques, environment, and working of the material. This was a brave attempt and props on that! This is some scientific metal and I would love to see another video of your deep dive and findings on this stuff. Seeing as you might need a million dollar lab to work it, giving it to the F it bucket would be totally cool. ✌
I think what is happening is that the tig welds burn up in places, letting oxygen in before you ever get in the first hammer strike. Here is something that might work. 1. Create a purged atmosphere work perspex enclosure where you can fit in some power tools and a small heat treating oven 2. Cut your pieces. 3. Put pieces and tools in the enclosure 4. Purge with argon. 5. Grind the surfaces shiny and dip in acid suitable to get the remaining oxide off 6. tig weld the billet, then tig weld your can around it 7. Coat the can in ceramic layer by layer 8. Cure the ceramic in the heat treating oven 9. take out of the enclosure, proceed to forge heat, smack it as hard as you can with the power hammer, you will only get a few blows before oxygen has crept everywhere again.
As you know, the tig welder liquifies the area of the arc and bathes it in inert gas, which allows the liquid metal to flow, mix and solidify (A grossly simplified explaination, I know), but I believe that is why it accepted the tig weld but failed with the coal forge since the coal forge is not a clean environment... I don't know enough about the metal to be certain, but it looks like you need to use an induction heater to heat, possibly while in an inert gas environment? I also get the impression the rest of the "forging" would need to be done while the hot metal is in an inert gas environment to prevent oxidisation.
You could try DIY an induction coil to heat it in a small forge that's being absolutely flooded with Argon/etc. I'm not sure if you could be hammering on it in an inert atmosphere though. You could probably investigate any special fluxes for Niobium too.
Not in normal atmosphere... you might get something that sticks together. But that's not what I'd consider a proper weld. But that argon setup is awesome! ;) I think it can work, you just overheated it. Sad that you fast forward the grinding at 2:35. Niob throws some of the most beautiful sparks I think...
a learning experience is is just that. You learned some thing new. why not use the failed a temps with another high temp metal to make Damascus. You pulled off the titanium knife though it took forever and it was beautiful. I watched every ep. of its making
Maybe using more ventilators to heat the forge up to a higher temperature and using a flir to confirm temps before going in. Since its not steel, you might want to take the" make sure twice forge it once " kind of approach
you can try this in a induction heater, may be can reach the weld temperature, but seal the canister with argon gas . or just try to weld with a low melting point metal between the layers,like steel. you can try with titanium, for tests if you can beat the oxidation problem just run to reach high temperatures(i supouse that titanium is cheap than niobium ) .
Induction forging in an inert gas might work. The setup could be a nightmare though. You might also want to try induction forging in a vacuum chamber. Vacuum welding might be possible even without a great deal of heat.
Looked at a bunch of comments. You should look into platinum soldering glasses to even be able to judge metal that needs to reach that temperature. #5 or stronger. Most induction can’t reach temps of 4500*+ they do make water cooled induction units, but honestly not worth the investment for a few fun projects. Talking to my platinum caster a few months back about the equipment he used made my jaw drop and head hurt. Materials that have such a high melting pointe also tend to cool fast AF once taken away from the heat. I think your first attempt with argon could have worked if you let it melt before your first blow. I don’t think you could have taken it out and hit it fast enough to really bond the layers. I’m not a blacksmith but I enjoy the content. Bummer it failed but it got my brain churning to solving the puzzle. With Pt small (1g) piece is easy to get up to temp, large ingot (14g) is significantly harder to melt. So maybe your argon and a way smaller pieces.🤷🏻♂️ thanks for putting the video out even though it didn’t turn out!💪🏻🤘🏻
Induction heating in argon environment is probably the best option to make sure no oxidations of any kind can occur. And a question I have is, does niobium have a surface oxidation like aluminium?
i know I'm a little late but if you REALLY want to do this I think a laboratory vacuum furnace would be the best shot since it's in a vacuum, but it would be incredibly difficult to do multiple passes it would really be a one-shot thing. Also I would assume they cost an arm and a leg.
We have a furnace at my work which uses a niobium element that gets to ~2000°C without falling apart or fusing. Also, niobium is quite reactive at elevated temps - it'll react with nitrogen above a few hundred degrees. A charcoal forge has no hope I'm afraid.
Ceramic fiber insulation blanket could help keep the temperature 🌡so the coal remains hot 🔥 for a longer period of time. Was also thinking of slabs in a box or triangle shape to keep the hot coals contained.
Dr. Frankenshteill's (yes, I consider you a doctor/mad-scientist) magnum opus was birthed with the Titanium Knife; all exotics with questionable true forging characteristics... Niobium is unforgeable at the temps you were able to produce. I love your videos and never stop testing yourself!
He Timothy like the idea of forging space-age materials, you could try switching your air for a different gas combo. instead of using plain old air to react with the coke if you added in some Hydrogen gas to your intake then you could get a more Reductive flame, it seems the problem is that there is too much O2 so you need to react it away.
I think its just not hot enough. Steel is forge welded close to its melting point so i wouldnt be surprised if niobium works the same. I cant see those sorts of temperatures coming from your setup though. At the blast furnace i work at, we actually heat up the air before we blow it into the furnace to get a flame temperature of about 2400C. But then again if you drop that onto the floor, the concrete would probably just start burning
You should try forging tantalum or scandium, also some of the other precious metals such as rhenium (greater density than tungsten or gold), ruthenium, palladium. It's even possible to get your hands on a forgeable sized chunk of depleted uranium (solid uranium metal) which has got a density about as high as gold so its a heavy bugger as well and should forge quite nicely. Thorium would also be awesome but much harder to get your hands on than Uranium, much more expensive as well but I bet it would forge nicely as well. Imagine you did a Thor's hammer out of Thorium, that would be awesome.

Its about the same hardness as titanium and the "ductility scale" is compared to iron. Sounds like some good stuff!

Been watching for a few months now, and only realized now that your Canadian ! Hey from New Brunswick !
A bit of an expensive project:
1) build a vacuum chamber with ports for an induction heater
2) form your billet
3) place the billet inside the induction coil, then clamp the billet in a large C-clamp (probably need a ceramic block on either side of the billet, the C-clamp needs to be large enough that it stays pretty far away from the induction coil)
4) Pull a vacuum, you need a high vacuum 10^-3 Torr at most, 10^-6 Torr would be better.

Most induction can’t reach temps of 4500*+ they do make water cooled induction units, but honestly not worth the investment for a few fun projects. Talking to my platinum caster a few months back about the equipment he used made my jaw drop and head hurt. Materials that have such a high melting pointe also tend to cool fast AF once taken away from the heat. I think your first attempt with argon could have worked if you let it melt before your first blow. I don’t think you could have taken it out and hit it fast enough to really bond the layers. I’m not a blacksmith but I enjoy the content. Bummer it failed but it got my brain churning to solving the puzzle. With Pt small (1g) piece is easy to get up to temp, large ingot (14g) is significantly harder to melt. So maybe your argon and a way smaller pieces.🤷🏻♂️ thanks for putting the video out even though it didn’t turn out!💪🏻🤘🏻
Either way Tim, good job at least trying to get it to weld. That's some crazy heat, and a 5 shade might not be enough brother....
Nice truck! Those are getting hard to find.
Induction heating in argon environment is probably the best option to make sure no oxidations of any kind can occur.
And a question I have is, does niobium have a surface oxidation like aluminium?
i know I'm a little late but if you REALLY want to do this I think a laboratory vacuum furnace would be the best shot since it's in a vacuum, but it would be incredibly difficult to do multiple passes it would really be a one-shot thing. Also I would assume they cost an arm and a leg.
We have a furnace at my work which uses a niobium element that gets to ~2000°C without falling apart or fusing. Also, niobium is quite reactive at elevated temps - it'll react with nitrogen above a few hundred degrees. A charcoal forge has no hope I'm afraid.
Ceramic fiber insulation blanket could help keep the temperature 🌡so the coal remains hot 🔥 for a longer period of time. Was also thinking of slabs in a box or triangle shape to keep the hot coals contained.
Dr. Frankenshteill's (yes, I consider you a doctor/mad-scientist) magnum opus was birthed with the Titanium Knife; all exotics with questionable true forging characteristics... Niobium is unforgeable at the temps you were able to produce. I love your videos and never stop testing yourself!
maybe...welding goggles next time...
He Timothy like the idea of forging space-age materials, you could try switching your air for a different gas combo. instead of using plain old air to react with the coke if you added in some Hydrogen gas to your intake then you could get a more Reductive flame, it seems the problem is that there is too much O2 so you need to react it away.
I think its just not hot enough. Steel is forge welded close to its melting point so i wouldnt be surprised if niobium works the same.
I cant see those sorts of temperatures coming from your setup though. At the blast furnace i work at, we actually heat up the air before we blow it into the furnace to get a flame temperature of about 2400C. But then again if you drop that onto the floor, the concrete would probably just start burning
Awesome vid. More unusual metals please.
Maybe using a par of soldering glasses might allow you to see the billet better. Since its so hot and bright.
This is pretty interesting. Guess I will stick around to see what else happens here.
You should try forging tantalum or scandium, also some of the other precious metals such as rhenium (greater density than tungsten or gold), ruthenium, palladium. It's even possible to get your hands on a forgeable sized chunk of depleted uranium (solid uranium metal) which has got a density about as high as gold so its a heavy bugger as well and should forge quite nicely. Thorium would also be awesome but much harder to get your hands on than Uranium, much more expensive as well but I bet it would forge nicely as well. Imagine you did a Thor's hammer out of Thorium, that would be awesome.
What are you welding the case with? It seems like the welds might have melted and that's what caused the case to break down and the oxygen to get in.
