"Making A Nitinol Knife. Part 1: Forging Nitinol" me, a guy with a welding degree and limited experience with Inconel, Nitinol's nicer younger brother, grabbing the popcorn and sitting down: "ooo this is gonna be hilarious" for the record guys: both inconel and Nitinol are "super" alloys. they don't really like working under hammers. or working at all. they machine like trying to cut steel with peanut-butter.
It seems like you need diamond saw blade, adamantium hammer and dragon scale anvil to work with this stuff. Not to mention nuclear reactor core to heat it. Not worth, considering the end result would be a Knife of Corrosion Resistance+2
You're running into fairly normal issues when trying to forge titanium alloys, I've been there. Short answer is that outside of expensive specialty equipment, stock removal is the only viable way to get anything out of it. And then when you go to try stock removal, it just chews through belts like no one's business, ceramic ones included. I have two different 50% completed titanium 6alv knives and I ran into the exact same problems when trying forge it - embrittlement, work hardening even when heated to glowing orange, and severe oxidation. Between the embrittlement and oxidation, my attempt at forging a usable knife was a complete failure. It is a knife shaped object though, so at least I have that. My second attempt, stock removal with a 2x72 belt grinder and ceramic belts was expensive - it ate ceramic belts like no one's business, it was both gummy and very hard to get anywhere, and it threw blinding white hot sparks everywhere. I got the rectangular block ground down to the knife blank outline and gave up after using a little over $100 worth of ceramic belts just to get to that point. I estimate that finishing it would be another two hundred dollars worth of belts, if I can even get a useable edge out of the end product and not just a wedge. Titanium alloys don't hold a edge worth a darn from everything I've seen. I think as knife materials go, they're right up there with plastic - can it stab something a few times? Sure. Will it have a keen, useable edge that can cut stuff a few hundred times before needing to be sharpened? Not really. So I've got tantalum next up on my list of 'exotic materials knives aren't made out of for very good reasons but I'm still going to try' list 😂
Steve I noticed from your first videos to now and always wondered why switched forges and noticed alot of people have your last type , does it work better or what, been subscribed since beginning ,really enjoy your videos they're honest and you represent most of us that don't have million dollar equipment,keep up good work thank you for all you do
I've been watching forging videos for a year or so, and I found this one fascinating. So many of them seem to go perfectly. It was really interesting to see how you were NOT able to successfully forge this.
We frequently use nitinol products in the operating room (I'm a certified surg. tech). It's used a lot in kidney stone retrievals (wire baskets) as well as guide wires for the bone anchors we use in various tendon/ligament repairs. Stuff is indestructible, just so flexible and tough. You can practically tie it in a knot and it springs back to original form.
Lol, "How good does this steel stack up against other steels for edge retention? Ha ha, not so good from what I can see." I love all the work and effort just to see if it's possible without any real reward. I love all your videos, nice work!

Wow!!!!!!!! I've never seen anything act even similar to that Steve. You gave it a helluva try. Only the navy would invest in something so difficult and expensive.
I'd never heard of this stuff until you posted this wonderful video, so thanks for expanding my knowledge. As noted by another commenter, this is why I watch. The way it behaves and the grain structure are enough for me to know I'm better off sticking with materials I know.
It's usually single crystal cast or rolled, then cnc cut, with an industrial forge, with large environmentally controlled ovens and cooled oil quench machines. My ex partner used to work for a company that did this for airplane components and let me tell you the machines in operation are amazing and absolutely huge. I wouldn't feel bad if you cannot achieve the precision, i mean, the presses are inside ovens that keep the metal at temperature and the atmosphere inside said presses/rollers/forges is argon or some other inert gas to remove the oxidisation problem, something you will find extremely difficult as you cannot do hands off forging.
Ya, thanks. I called a couple places about rolling and that’s what they said. Heat blanket, inert atmosphere. Ridiculously expensive to roll a piece they wouldn’t even quote it.
@@GreenBeetle totally, just to start those peices of equipment costs thousands. I remember being told they're on 24hrs a day and only turned off for maintenance, seeing as it takes 24hrs to heat everything back up to temp and ensure repressurisation of the system. The company that my ex worked for also had large orders booked upto a year in advance, so their forge time is often entirely spoken for. If you were to go to some of the bigger companies and speak to someone in their quality control department you may have more luck as they do small test runs fairly often to check the metals on output meet specifications and may be willing to work on the scale you need.
"You can be in my arms anytime" bahahaha.... not my choice in music but keep bring the heat man! Also, your SPEC ops ability to get crazy materials is great. Perhaps a camo Damascus T-100 robot next? You got this bro! Great stuff man and more please!
Best forging channel around. Anybody can film them banging on hot metal with no dialog (and dang, those are BORING!!), but the descriptions, explanations and failures are why this is great stuff.
Awesome video Steve! The oxidation was insane, really cool to watch. Keep up the great work, its always a highlight of my week when you post a new video.
As a metallurgical engineer I love seeing the phase diagram but sitting here crying at the attempt to work it. Almost seems like it could be cast but its melting is somewhere around 2300F so..use a coal forge if a gas cant make it and see if a heated mold could accept it, maybe even cool it while in the forge lowering temp gradually. Crazy stuff.
I once sent a kid to the tool room to get me a metric crescent wrench. It took an hour, but darned if he didn't come back with a real metric crescent wrench.
For an easier material to work into a blade that's in the EOD realm is frag. I've done a few projects with it before. I'd be happy to send you some if you'd like.
Cheep roller for sheet, two offset cylinders opposite direction for rotation, and the work fed in the direction of exit, and the offset comes closer, squeezing the work until it spits it back out towards you, and at a relatively safe speed.
Nitinol is weird stuff. One of our plants at work makes it. Super strong and has shape memory when properly heat treated. We made tires out of strands of nitinol for the Mars rover for NASA among other things.
I just watched your UA-cam “Forging a knife from springs - part 2”. Needless to say I’m an admirer of you work. Your smithing is neat, precise and well executed. And the bonus is always a superbly forged blade. Thank you for the excellent videos. I would ask if your knives are for sale? I look forward to your next video. Good forging.
This reminds me of world of warcraft when you try to max blacksmithing skill. You have to get it to max level, then take a quest to learn how to craft special gear. This is what green beetle is doing here. Good luck on your quest sir!
Next, Steve makes a knife out of frozen butter. Word on the street is that it's fantastic to work at low temperatures, and, in the long term, it can kill you by getting your right in the heart.
Known about nitinol for a while, am curious what bolo's on a nitinol cable would do, if cooled, then hit the target, would the warmth make the nitinol react?
Maybe an induction forge could help out with that. Maybe try and get a sponsor? Or in you have enough to invest in one. Very good educational experiment. I like seeing smiths trying new metals and alloys out.
Talk about "where angels fear to tread", yeesh. I would be too scared to even try making a go out of it, thanks for making the video 👌🏽 If you still have some of the damaged/highly oxidized chunks and you're willing to part with them as your shirt instructs, "acquire currency", I'd be happy to oblige and have a piece of metallurgical history.
Wow some how I missed this one. I would have just sent that sucker back to dude. I guess there is a reason you don't see many knives made from this on the market Enjoyed your video and I gave it a Thumbs Up
🤣 Was just thinking about this yesterday, 5 min of google convinced me that nitinol is stoopid. Now I know for sure that I wont waste any more braintime on the idea😁
My suggestion: crucible and a mold. Hard to believe that it wo't hold an edge as hard and brittle as that stuff is. If you find the secret to working it it should be like working ceramic and keep an edge forever...
Now that is some insane material to trying in Forge out into a knife wow always ♥️ to ⌚ your there so interesting and easy enjoy Watching your videos ♥️✌
This stuff is like AR500 armor plate or Armet steel . Without the big boy tools it super hard to use. There was a bike frame company that tried to make frames out of Armet tubes in the early 90's. They had tons of problems because they went through so many grinding wheels. I think the finally just abandoned the product.
Steve- Just a thought on the Nitinol Steel. Is there a possibility the round piece could be chucked into a lathe and you could make turnings of the Nitinol, then place those turnings into a canister? Maybe then add some 15N20 powder to the canister with the Nitinol shavings? Would this make the material more usable for a knife. Yes it would be a mixed steel knife, but it could yield an interesting Damascus pattern, plus make the material more workable for the knife... Just a thought??
Gak! What torture :/ I am on the edge of my chair for the second part. I wonder if the finished blade will be too brittle? I wonder if there will be a finished blade? Great stuff, as usual!
Hey Mam, Love Watching your Videos they are Awesome!! when i was watching SHURAP make a cannister knife Right befor he closed the cannister he put Some Pepper, A Chili Pepper and maybe one more thing but after heating and smashing a few times the Cannister shell came right off.. crazy but i thought maybe you knew of it? anyway your amazing man!!
@@GreenBeetle not sure how I feel about that. I am loath to waste material, but if it’s from one of the very first melt batches I’d say it should be in a museum. If you still have the samples, it would be interesting to listen to the sound they make when tapped at different temperatures along the austenite/martensite transformation. Just like the event that clued the researchers into the structure change that happens with temperature and strain.
So the yellow stuff is nickel oxide then? Is it harmless? Because I have had stuff like that happen on salvaged steel. I had made sure to remove any zinc coating because danger and seeing unknown stuff pop up anyway got me scared.
Because there is now a part two to this, I have to go back and watch the first part. I may have prematurely and inadvertently killed those brain cells.
Id like to say you shpulkd get it hotter so its softer, but ypu know what you're doing and the properties of both metals together males it appear that they dont like eachother. Maybe witn the addition of something like a tin impurity would help.... but they really seem to want to separate and form grains creating large grain boundaries and be more like mud rather than taffy.
content like this is precisely why this is one of the best knife/metal working channels on the Tube! thank you for sharing

Whelp I guess I’m not sleeping. Got green beetle vid to watch 🤷🏼♂️
Man you messed up real good 😂
Love it
Man that stuff looking like an absolute pain in the rear to work! Titanium works so much better in my experience with TI but I’ve never worked nitinal
If the beetle can't make it into a blade then it's not happening lol. Great video

So the yellow stuff is nickel oxide then? Is it harmless? Because I have had stuff like that happen on salvaged steel. I had made sure to remove any zinc coating because danger and seeing unknown stuff pop up anyway got me scared.
Don’t know.
More likely oxides of titanium. Of you heat titanium in a forge it turns yellow orange color
What would really be cool if you could make the handle of the knife from the horn of a unicorn, that would certainly make it one of a kind
Very interesting material !!!!!!!!!!!!
This is really cool. I have no idea the science behind most of so maybe I'm stupider then the Nitinol
Is there any place to easily order this stuff in a reasonable size online?
Next time, can you make a knife out of a mithril-adamantium alloy...
Wow that was experience in frustration.
Steve (GB) send a piece up to Canada to Tim Dyck Black Smith he deff loves playing with the exotic metals
Because there is now a part two to this, I have to go back and watch the first part. I may have prematurely and inadvertently killed those brain cells.
Id like to say you shpulkd get it hotter so its softer, but ypu know what you're doing and the properties of both metals together males it appear that they dont like eachother. Maybe witn the addition of something like a tin impurity would help.... but they really seem to want to separate and form grains creating large grain boundaries and be more like mud rather than taffy.
Where to buy lots of cheapest nitinol? Can it be made at home by smelting titanium and nickel wires together in vacuum or oxygen free environment?
Can’t make at home that I know of. Try sb specialty metals snd good luck
Great videos man!👊
Ever think to try doing it cold.
not even for a second
5:10 that material is giving you the finger with how little was scratched off when you tried to cut it.
Titanium is a highly reactive metal. Needs to be worked in an inert environment (e.g. argon)
Got the notification for your new nitinol vid but it says its private.
Was the bow in 14:05, but you really hid those shoes! :-P
They’re easier than the bow!
