nitinol wire

[mrorangelightning]

Just looked this up from a chemistry revision guide...

Thats too cool :D

[packleader1215]

Be sure to look at Jacque Fresco's video on SHAPE MEMORY METAL for preventing car accidents.

I would like my car's body to be made of Nitinol so that when I crash, all i need to do is pour some hot water over it. And every time i crash i will get a unique paint job.

[Veehmot]

@TheKrisHimself That's what Jacque Fresco designed years ago, using this same metal. He designed a car made by Nitinol, so if you ever get hit (something somewhat unlikely because of the sensors the car have), the car repairs itself :)

Watch Future by Design.

[sovriegn117]

What happens if you tie it in a knot?  does it break itself trying to go back to the shape?

[questionwhatyouhear]

@sovriegn117 I've tried this - fortunately it doesn't break :) The stuff is suprisingly soft for wire, it'll just lock up at the knoted point, forcing you to take it out untie the knot, and then put it back in the hort water for it to continue getting back into the original shape.

[0lolop35]

its true TOH oh wow XD

[EvilRabbiMAn]

next step is to warm the key.

[Ishudbriding]

HHaha UFO material ... Wow

"Nickel Titanium Naval Ordnance Labratory"

That's what nitinol stands for

"Naval ordnance lab". located in Maryland, USA not outerspace

[Films4You]

If you pass an electric current through it will this heat it up and make it return to shape?

[shgtshgt]

@Films4You

Yes. You can use this for actuators in robots.

[Films4You]

@shgtshgt Thank you :)

[CARE2DOTCOM]

Anyone interested in how we discovered Nitinol..?

It's quite the story....

[ObliviuxProductions]

@CARE2DOTCOM

Sure why not

[CARE2DOTCOM]

@ObliviuxProductions

An out of the box idea peehaps but stranger things HAVE happened.

Google "The Curious Dr. Cross" and dont stop there..

Enjoy ;-)

[hunterziegelmann]

make a toy car out of it then smash it and stick it in water and BaM fixed

[Bastige56]

@hunterziegelmann Why does it have to be a toy car?

[J4kobB]

if heated, it changes back to its original shape.

but how can you change the original shape its changing back to?

[yourcouchisbleeding]

when heated, it contracts. when cooled it returns to its normal state.

lol... look at all the idiots crawling out of the woodwork calling this UFO material, it's just a novel demonstration of superelasticity.

[CARE2DOTCOM]

@yourcouchisbleeding Look at all the lazy sheep to dumb and lazy to ever bother to track it's development let alone shut up if they dont know.. Oops..! Did I say that out loud!?

Sorry, carry on Mr. MS..

[yourcouchisbleeding]

@CARE2DOTCOM I'm sorry but your rhetoric doesn't lead us anywhere. If you're insulting me, then I don't care. But seriously. . To assume these materials and/or concepts are of extraterrestrial origin rather than the product of human ingenuity seems ludicrous to me. Assume what you will, I will do the same.

[npc223]

@J4kobB with a really, really big flame

normally you'd shape it into what you want it to be, then heat it to 1000 degrees farenheit for a a few minutes

[awesomefrankrapid]

nitinol is the metal of the angel of fire.

[GravWave]

Guys, it's not the Roswell material. The Roswell material could not be "felt." It gave no sense of touch. Nitinol can be felt.

[EasternCalifornia]

PTTLAKSF!

WHAT THE FUCK? 0_0

[KCwellard]

Roswell

[Metal66Sick]

This is the reverse engineered product of the material found from the crashed UFO at Roswell in 1947.

[mungo1414]

@Metal66Sick haha^^

[rokerguionbajo07]

GODLIKE

[ohaleceiffel]

NITINOL= Ni ckel Ti tanium N aval O rdinance L aboratory

[wompasdub]

^ this is true. This video is epic.

[themoreorless]

Hi...a question:do u know the diameter of your nitinol wire?i mean, in the video you have got a awesome effect, never exceeding the martensitic yielding point( 8%)...but we can't do that with a 0.015 inches nitinol wire..any suggestions?

[tiguy99]

Roswell anyone?

[iggie200]

yeeeeeep

[johnkollor]

I take it thats what they make those bendy glasses out of?

[danius2]

Anyone know this guys name? i love the sound of his voice

[KIRBOOMC]

That is really clever they say it has its own memory

[usernameunauthorised]

I mean um... something like that... how do you set what the predetermined shape is going to be..?

[SPiFFrgr]

You predeterminate the shape in hot. Later it gets cold and you can stretch the wire in any aleatory shape. When you apply heat again, it returns to its predeterminate shape.

[usernameunauthorised]

oh.. k that makes sense. thank you

[usernameunauthorised]

how do you predetermine what the shape is? :(

[Asenroth]

Why this "metal" became a word just in english instead for example a japanese ? : o

[Slaer07]

so how do you control the unscrumpled state of the wire?

that is, what if I don't want it to say "toh" when I apply hot water? What if I want it to turn into something else?

[arlysutroa]

This behavior has been known for over a hundred years. A number of ferrous and non-ferrous metal alloys undergo stress or temperature induced reversible shape transformations. These transformations were first observed 130 years ago by a German metallurgist named Martin and hence they are called martinsitic transformations.

[danielps777]

TOH

[zingymosquito]

inmiddle school my orthodontist showed me this stuff bc its the stuff used in braces and the warmth from your mouth gradually bends the wire back.

[leem666]

What happens if you drink really hot water :O

[pacoaliv]

toh yllaer

[ivandefr]

your Intestine will turn into the shape of H-O-T

[pacoaliv]

this is the shit

[Grinch88888888]

A good old englishman showing a good old bit of wire!

with such quotes as:

"Goodness me"

"Thats nicely done"

"scrumple"

[jilotepero]

Madame Sarkozy

[sb6lb3]

with a wire like that, you can make an orthinotpter

[06stephend]

wat is that?

[schoschie]

You mean an Ornithopter?

[juavojuana]

this would be promising in making more human looking prosthetics if you ask me, just get the right robotics guys in a room, i think it could be done

[Euphorlc]

you have to think about more then just the car in an accident. would this metal protect the passengers inside at all in an accident?

[Resetti64]

This would be good for car collisions.

[wiqqido]

you sound like willy wonka dude. that is awesome.

[rooknoc]

is it expensive material?

[CustomBuild]

cool

[viksra]

AMAZING!

[solojony]

Its used on antenna of satellites too, to deploy them extending without need for motors.

[rejoycement]

where do they get the heat tho? i thought space was suppost to be like COLD

[solojony]

I suppose they apply an electrical current to the wire, that can get very hot. Google for: nitinol antenna satellite, found several.

[javiseni]

Si lo que se ve es real las aplicaciones son inmensas, tanto para el bolsillo como para la ecología, dando infinidad de salidas a estos materiales. Por descontado dejaríamos en paro a muchos carroceros.

[eliperere]

esto se usa actualmente en la microrobotica y en la robotica en general

[Kilomph]

You're speaking jibberish.

[wolfmankurd]

One of it's best uses is in suturing. Put it through the tissue. Detach needle and the trigger then it deforms into a good knot! The use when they need a lot of sutures fast, like heart valve replacement.

[Prodgial19]

TOH

[kbisogni]

My friend works for a company that produces this type of wire. The number of uses for it is staggering. Generally it can change shape due to an electrical impulse. It gets its shape memory from a particular stretching process.

[ebonyrolla7]

i love the picadilly bowl...old man

[storlied]

Looked like a huge pube at first... that is cool though.

[mkiwiet]

very cool -

How is the memory state set to "HOT" in the first place?

[wolfmankurd]

Good question lol. By heating to very very hot temperatures, shaping then cooling them rapidly. Typically 500°C.

[BraDRoBBo]

Wheynz!:P good stuff ;)...

physical memory ont scene!

[Licurgoknox]

this can't be real

[hoss1962]

Showing off your fortnum and mason bowl, huh?

[SupercarGS]

NItol is kwl

[Supercar430]

wikid i want some!

[maxhere]

nitinol is awesome

[ANBUwarrior13]

KOOL!!!!!
