it's super cool to feel in person. that hot/cold effect is even more than you'd think (check out the facial reactions in the video)!

hell yeah we use it dentistry and are also taught all about it ,especially for root canal instruments and for braces and orthodontic appliances.. but just like you never knew it was used in so many different ways ,crazy that all these fields have this material in common

I first read about it in the late 70's

@@thesmarttirecompany For how long does the bent part stay warm?

@@slav_K0 if you are holding the tube like in the video, the heat will linger for a while (really it's your hand holding on to it). Otherwise it would dissipate into the air if it were held in place. However, for a tire rotating at high speeds, there is not really any time for the heat to escape, which is perfect because we get to "recycle" that heat energy instead of turning it into waste heat.

Wait... so why when I had braces as a kid did they need to constantly be tightened and adjusted? Or is it a newer thing in orthodontics?
Edit: Also my teeth wanted to return to their original position as well... 5 years of braces and retainers did nothing!

Nasa and Boeing studied also chevrons with shape memory alloys, bending towards the flow of the jet exhaust when taking off or landing to reduce noise( by introducing mixing vortices) and straighting the chevrons out of the flow when cruising to increase performance

I wonder if there are ever any scenarios where that would be not the required behavior. What about those Antarctic resupply flights or airfields in Nepal or Tibet: you might not get the vortex generator to flip back up....

One of the big ones is just that it's pretty expensive

@@panner11 So were computers back then. But the costs came down massively as they improved and got better at making them.
So if it really is still so expensive, the question is what's stopping them from improving and getting better at making them?

@@asherandai2633 the material is titanium, how many things are made of titanium? Shows you how rare they are

@@pkmnogosari6091 titanium is the fourth most abundant metallic element, and the ninth most abundant element overall. It’s not rare at all, so it shouldn’t be so expensive.

​​@@asherandai2633
Semiconductors became cheaper because transistors were made smaller and smaller. Meaning less material was needed.
You can't apply that concept to something like gold, for example. It's expensive because it's limited.
Both Nickel and Titanium ore is very limited.
Nickel is can only be mined in a few placed on earth in significant amounts.
Same with Titanium.
Both metals have very high melting points (need a lot of energy to work them into shapes).
Hence why nickel alloys are used in jet engines (because it can handle crap tons of heat).
The bonds between Titanium and the stuff it forms a compound with in the ores require a crap ton of energy to break.
Extracting Titanium from ore will always be energy intensive. There's no way around that.
Titanium is very reactive so it needs special environments and tools to be worked. An inert atmosphere and tools that won't contaminate it.
Working with both Titanium and Nickel are both very mature technologies. Both metals are used extensively in the aviation industry.
There are 35 000 Commercial aircraft existing now, alone. Most of them making extensive use of both nickel and titanium. Everything to make it cheap in terms of energy has been done.
Then the electronics industry also uses a lot of nickel, and increasingly so with lithium batteries. Only a few countries are blessed with Nickel and Titanium ore. E.g. Russia. Hence why nickel prices are skyrocketing.
In other words, using nitinol for a lot more stuff will increase Titanium and Nickel prices. Making it more expensive, not cheaper.

It's sad that it's never found widespread usefulness.

​@@RC_Engineering it just did

They've been theorizing uses for 40 years, yet when you look around do you see this material on a daily basis?

Is the application similar? Does applying heat to it help it “set”

Isn't it also used in braces?

@@Vadow789 Yes, in self ligated braces.

@@Vadow789 My orthodontist used NiTi in my braces about 30 years ago. I'll never forget him applying cool and watching the wire go limp then applying heat and instantly regaining the shape for my teeth.

@@xGaLoSx Well.. to show the difference. It is still called a tire after all. And seeing it getting shot by a bullet, not only not getting punctured but also not getting bent to unusable state, as a wheel, is kinda amazing.

In the context of racing tire pressure is usually used to control heat. Low pressure tires make more heat than the same tire at a higher pressure. They are just trying to target a specific temperature for a given tire compound.
It could be cool to see it used to increase efficiency of vehicles with rubber tires. In the straights you could reduce the contact patch of the tire to reduce the coefficient of friction. In a corner it could do the inverse.

I'm sure shoes have a place here

i kinda doubt it'd be used for tires cause it seems like the coefficient of friction isnt going to be all that high

This wouldn't really work, because it only goes back to it's form when getting warm. You would have to manually reset it when it gets colder outside, but it would be a cool concept.

It would write "hot" when its hot and "cold" back when the temperature drops

Wow thats actually so cool. You could make objects bend to create shade when they're warmed by the sun as well

@@mladenivanov5630 insecure much?

Did you learn about bullshitonium yet?

I once designed a solenoid valve that used a nitinol spring. The problem I had was the fatigue life was not good. I would get springs breaking at 100k cycles and I needed 10x that. So I abandoned nitinol for spring applications. This was 15 years ago. Have there been advances that have improved the fatigue performance? I assume tires would need very good fatigue life.

@@alexkram it’s possible that the strain was too close to the maximum of roughly 8%, which over time could weaken the material to the point of breaking. 3-4% strain is ideal for longevity, and would make for a relatively life-long part.

its*

@@alexkram I'm also an engineer at a nitinol device manufacturer. A big factor in fatigue life is alloy purity. Companies now offer alloys with extremely low inclusions (ELI from Confluent, Enduro from Memry, etc.) You would have better luck with those alloys when considering fatigue. They are fairly recent advances so weren't available 15 years ago.

How expensive is the material? Could those jeep wheels be a factible product?

Yes, so many possibilities!

I really wonder what's the downside of this material? Is it just cost?
Cause all I've heard of it is super positive, if it is as good as it sounds we could have great developments in the near future

@@gabiferreira6864 As far as my project went, you'll order based on your specifics. I needed 1mm radius wires which had memorized as a straight line. I cut it in the size of my antenna and because of the memorized shape, I could completely bend everything to fit in the container. However, if you want to memorize custom shapes like the "Ve" or "NASA" we saw in this vid, I'd suppose you'd need to send the manufacturers specific details. My thesis was almost exactly 2 years ago, so maybe things have changed. It for sure wasn't like your typical DIY shops back then, but that made the experience feel more special

It is because airless tires have some drawbacks such as increased weight, higher rolling resistance and higher cost, which have prevented them not yet from being widely used in passenger vehicles.

@@bjarne9321 Also without a very durable/fast way to change things like vortex generators you are limiting an aircraft's maneuverability substantially let it be agility or range.
Seems like an excellent material for commercial airliners running certain routes and niche projects alike. Can't wait to see if something similar can be made with different materials and/or properties.

the reason is that they feel like sh*t to ride compared to pneumatic tires. They are utility wheels first and foremost.

Nickel and titanium are fairly expensive. I'm not sure it would be practical to use these tires on a normal consumer vehicle.

@@jonadabtheunsightly I'm not so sure about that. We're already to the point of using carbon fiber on certain parts of the engine block, namely the pistons and connecting rods. Material sciences, 3d printing, and strange new ways of looking at engineering have dramatically changed cars before, and once consider super-exotic, are now common everyday things. The tire pressure sensors in my Mazda 2 were once debuted in the Porsche 959, at one time the fastest car in the world, as such an example. it's less about cost, and more about practicality. Someone mentioned comfort. I'd rather have the occasional flat than have a ride like falling down the stairs.

is it just the cost or is it something else?

@@squidwardo7074 Oh, I'm not an expert so I was genuinely asking.
Realistically, they will need to be covered so they don't fill up with junk and change the driving dynamics, and they'll need rubber tread for traction... A puncture in the tread wouldn't do a whole lot since the tires wouldn't be pressurized which is nice, thought you'd still have to patch it eventually so the tire doesn't fill up. It could have thinner rubber on the sidewalls (no pressure) but overall would probably be about as heavy due to the metal. And the price of course would be enormous. Even if they work out economy of scale issues, you're talking about doubling the cost of your tire in metal costs alone. And the only benefit is that you can't pop a tire. Probably worth it for the military and maybe some other niches. Might make sense for planes. And of course rovers.
Its cool tech though so... I mean, I hope they figure out all the issues. Oh, and shape-memory metal is super super useful in a million areas they barely touched on :P its just a bit pricy

Pretty sure it’s just the sheer cost of making it, not profitable I suppose

@@briteeyes2133 it's hard to appreciate just how good pneumatic rubber tyres are. The rubber fulfills three roles at the same time (containing the air, deforming around unevennesses, and giving traction to the ground), whilst the air manages to support a big weight with very little obstruction to the deformations / rolling.
Those nitinol tyres do a formidable job at replacing this functionality, but they can't do it all as well as pneumatics. Unless you need your tyres to work at insane temperatures or survive deliberate perforation (and can't use liquid sealant), there's just no point.
