Nitinol Amazing Shape Memory Alloy

In this video I talk about an amazing type of metal called a shape memory alloy. The specific one in this video is called nitinol. It is an alloy of nickel and titanium. It forms an amazing structure that "remembers" its shape even after deformation when you heat it up slightly. If you want it to have a new shape you simply have to heat it until it is red hot and it will form that new shape that it was in when it was red hot. In this video I see if extreme pressure from a hydraulic press can make it form a new shape. I was amazed at the results!

I know this is a very old video, but I just wanted to post that pressure actually causes heat. When you used the press to squeeze the wire, you generated enough heat to cause the wire to reprogram itself. Very cool video. Thanks for uploading this experiment.

@ryandurand9769 4 года назад

The pressure would have created heat during the press so that's why it deformed and stayed deformed pressing it's still a form of energy that ends up discharging into the metal being pressed

@KarstenJohansson 3 года назад

I have a number of NiTi spools, as well as a sort of "hydraulic" lift made with NiTi (looks like hydrolic or shock absorbers, but it's a NiTi coil instead of oil inside).They are very cool to experiment with. I suspect the reason crushing works, and I was just as surprised btw, is because the crushing would create its own heat, and probably just enough to barely set it for that coiled shape. I think that is worth its own experiment.

@GG-od2tr Год назад

A most underrated discovery that should be utilized in engines as it gets stronger the more times it goes through phases of memory states. Unlike all other metals deteriorate from the composition of change. I should love if you spoke on time and how little you know it.

@JM-lh8rl 7 лет назад

hockeytalkie18 Since the press made the atoms' bonds slip by instead of stretch like bending would do, it assumed that structure as its new shape. When he straightened it, he was stretching the _new_ structure, the one that was already curled up

Pressure makes heat I would venture to say when you crush metal with tons of force it heats up. Great video

@iwh7 7 лет назад

Hi there, interesting video. Thanks a lot. But are you shure its from the pressure and not from temperature building up while it got squeezed in the press? As much as i know you define the shape it memorizes by heating it up to a certain temperature und forming it. Thanks for an answer.

@alstenmart 6 лет назад

You are right, it gets form under temperature and if he would apply more heat before putting into water it would straightening more.

@imnotcreativeenough8453 3 года назад

@ufowatch 3 года назад

pressure equals friction and friction equals heat. so when it was crushed it did heat up.

@ufowatch 3 года назад

i have been thinking about it alot now and i truly believe this my hold a much bigger secret no one sees yet! this seems to contract and expand super fast with a small amount of heat right? so finally we can make a true perpetual motion device! like a sterling engine only much more efficient. this is it!

@thejanssen6030 3 года назад

Does this release more energy returning to its memorized shape than it takes to move it out of its memorized shape? Doesn't seem like it. Springs contract and expand super fast with zero heat which would seem to make this less efficient than a spring as a source of mechanical energy.

@ufowatch 3 года назад

@@thejanssen6030 One square inch of Nitinol material generates a shape returning force of + 30,000 PSI. does it take that to bend it when it is cold no it moves easy. i have experimented it has a ton of usable force but when cold it bends like butter. so yes it does in my opinion release more than it takes in if done correctly.

@thejanssen6030 3 года назад

@@ufowatch then in your opinion it is breaking the laws of physics and creating energy, and the RU-vid comments section is exactly the right place for that type of theory

@logic2818 Год назад

This technology was actually found from a reverse engineering program that used recovered materials from an Alien craft (actually an Alien drone) that crashed in Roswell NM in 1947. The recovered materials from that crash had metals that were free forming and could be crumpled and returned to their original state instantaneously. My grandfather helped develop the technology in Maryland at the Naval Ordinance Laboratory in White Oak in the mid 50s until it's release in 1959. Much later he revealed to my mother that the catalyst for the idea of memory alloy had come from a reverse engineering program in Bethesda that had recovered materials from the Roswell crash.
