How to shape Memory Metal | Nitinol wire experiments | dArtofScience
Lets see how to shape memory metal and nitional wire experiments
This is not a DIY but a demo which shows you every step.
Steps to shape memory metal
1. A line drawing of the required shape is made
2. A jig for the required shape is made so that the wire can be held tightly in the shape while being heated, otherwise it snaps out
3. The assembly is heated till the whole wire has a dull red glow
4. Then it is quenched in cold water
5. The wire is removed from the jig and the extra bits are cut off
6. The wire is gently twisted out of shape and thrown in hot water

Could you braid this into a rope, then take the rope and make a bigger spring? Get more lifting power?
nice video sir
that was nice
Great video, How many cycles of returning back to it's heated shape does it have before it loses its shape/springiness?

many times but we spoilt it but trying to lift weight with its memory power

I was about to ask that question. I was wondering if it would make a good material to make harmonica reeds.

Great Video, what temperature is needed to break the old memory structure and build a new one? How often can you bend/redo before the litinol wire breaks? Thank you 😉

Temperature required was about 300 degrees to get a new shape. I think. It's been a long time since we did this

Do you know the transition temperature (af) of the alloy you used?

thank you.
It’s not a parasitic worm, it’s a piece of Nitinol Shape Memory Metal wire. There are plenty of KZread videos of this.
Is there any info on home made Nitinol?

in our case it got spoilt picking up the 1 kg weight...and lost its memory/shape

is it just wire or is there metal plates as well ?

Whats the length and diameter of the nitinol wire used?

both really dont matter in this case because there's is not too much choice that is available on the net. but it was less than 40cm i guess
OVNI
