Not really, high compression produces heat, such as being crushed in a hydraulic press. It was that heat that caused the wire to 'permanently' deform. The pressure generated enough heat that it rearranged the molecular structure slightly. With such thin wire, surrounded by the large mass of the press, the wire cooled down and took on the new form as the 'default shape' by the time the pressure was removed and he picked it up. If you bent and anchored a nitinol wire, then heated it with a torch it would do the same thing, meaning that the molecular structure would relax and then solidify with the new shape as the default. Try This: Take a nail, or a piece of wire, and try to hammer the end flat using a hammer and an anvil; striking hard and fast. Now touch the nail/wire where you flattened it, it's hot huh? Same thing happened in the press, just with one heavy strike.

The pressure of the press caused heat....

Actually... crushing the hell out of that wire would have made enough heat with friction to reform the metal to that shape. so cool that I subscribed

Reeeeeeeee

Action Lab, new fan and thank you for your videos. After watching this, I had a thought. Did you try boiling water? What if you froze the wire then curled and pressed it? Curious if the press caused levels of heat at different points in the wire that kept it from returning to its original shape.

why don't they make ear phones out of this?

Why not dude? Just have a system that pushes water out with the speakers. Just like the new apple watch its waterproof so you can go swimming with it and if it gets water in the speakers the speakers givebit some bass or something like that to push the water trapped in the little holes search it up bud

Smart

The wire got hot by the pressure of your hydraulic press, forcing it in a new shape. Make it back straight by hand, and then dump it in hot water to make it curl back to the shape it had after pressing it.

It's possible with the increase in pressure caused by the press that it heated up from the friction causing the slip to occur. as when the press applied X pressure the coils were pushed against each other which created intense heat and caused it to crinkle also causing the bumps you saw when the coil was flattened.

I'd like to wee you retrain that strand into a tightly coiled spring and see if the "crush" memory can be erased. That, and see if flattening a round wire in a coiled shape that does not cross itself will produce a wire trained to retain that position when activated, or if the super-elastic resource that nitinol affords can be accessed by a mechanical deformation of the wire.

I was looking at other videos on Nitinol and was thinking it would be perfect for Action Lab...but then here it is from 2016.

You can test to see if the heat from crushing is what actually reset the structure, or if it was truly the pressure by simply conducting the same experiment with a fresh piece, except running the press very slowly.

Your pressure caused high heat and "reset" the memory of the wire

was that the same bandage from the obsidian incident?

"I heated up the water a lot, almost boiling" *Proceeds to put entire hand in water to retrieve wire*

cool nice educational crush

Hydraulic presses must ALWAYS win

Awesome

interesting metal for sure

you should pour water while its geting crushed to see if it will slow down the press

I'm not sure if this is right, but isn't pressure a form of friction? If so, wouldn't that create heat to influence the atoms in the metal to slide over each other easier?

Yes, it does heat it up, but it needs to be red hot for the new crystal structure to form, and it definitely wasn't that hot from the press. So I think it was just purely from the pressure that caused non-elastic deformation.

I agree. It may have gotten hot enough in small local areas momentarily. Without it being noticeably hotter overall when pulled from the press. I suggest crushing it much slower, like over a 10 minute period. I'm very curious if the deformations and dents will spring out if this is done.

So when you pressed the wire is it possible the pressure from the press caused a small amount of heat from the friction from the wire Smashing against it's self. Could this possibly be why it took a new shape? Thought about using a thermal camera to view while pressing and releasing..

I've been expecting it as high pressure applied fairly fast means fast temperature rise. You may think You've been squeezing it fairly slow, but relatively to thickness of the wire it was fairly fast. Very high pressure means very high temperature rise as applying pressure You basically put in the squeezing energy into the bent wire - that much energy You applied would require a lot of time (comparing to squeezing time) to transfer the heat on the vice and air surrounding it. If vice would be small assuming it wouldn't brake it would got hot too unless work would be done slowly letting it radiate the heat out to the air.

Your finger is still cut from the obsidian ball!

Skeleton Made of pure Nitinol

You just break the good wire ...

How reliable is the establishment of the set-point of nitinol at the manufacture level? for example - can one order nitinol with a 0.5degree tolerance in the temperature set point. e.g can we order nitinol with a set point of 45+/- 0.5degrees

Would increasing the water temperature more helps it get its real shape before you pressed it? Thinking the water didn't give it enough energy to gain its original shape.

Friction heat... Might do the thingy with the stuffs

Sir, did your hydraulic press just exclaim, 'Whheeeeeeeeee !' excitedly once released ?

You re"set" the shape when pressing it because of all of the heat during the process.

I don't think he shape set it in the hydraulic press. There's likely some plastic deformation which is preventing it from going back into the straight wire

It just lost it's memory.

You probably "reprogrammed" the shape of it when you crushed it

Omg this is a new record I'm so early

Well the crushing kind of is pressure. Pressure=heat. It is forced to be in that sharp under that pressure.

Black Knight No. To change the structure, it needs to glow red. That's much more heat than the hydraulic press made.

It is even used in some knives

Did the pressure emit heat in the process due to friction?

I wonder if the work associated with compression would have heated it

I have bought nitinol the Form is straight. Can i "programming" a new Form to it? If yes, how?

How strong is this metal compared to other metal?

This material id to be considered as Iron mans armor

guess the press heated the metall

Doesn't pressure cause heat...?

The amount of heat from concentrated pressure would easily get above 500 degrees. Cant say this test was conclusive without expanding on that possibility.

No way... It would have burned him when he touched it. No way it cooled back down from 500 to room temperature in the few seconds he took to grab it after pressing it. It would have only heated by a couple degrees at most

You're an engineer right? Make a small robot with it

What if you made a Nitinol coin and flattened it in a hydraulic press then threw that into hot water?

skynet should have made a terminator out of nitinol

You gotta heat the water. That water doesn't seem so hot
