What is NiTiNol?!? Nitinol wire and examples!

Nitinol memory wire. What is it? This futuristic material can "remember" it's forged shape using the unique crystalline structures of austenite and martensite. Let's learn what it is used for and how to forge a new shape using science!

Finally I found this Nitinol after I saw it 38 years ago. I was not sure what was it. Thank you 🙏

[@constiii553]

Oh wow! This is really fascinating information! There are so many exciting things that we don't know about in the world! You just totally saved my grade!😁

[@LifeMeetLightning]

I took a metallurgy course as part of my work's career advancement program about a year ago. I spent 40+ hours learning way more than I ever thought I needed to know about metals and their uses. It only occurred to me now that it didn't even mention Nitinol. I remember learning about it back in school. It's cool stuff! Great video, guys!

[@DestructiveCreativity]

Thanks! It really fell out of favor in the mainstream around 20 years ago. But it is making a comeback.

[@tunashark3029]

Nitinol was created by my great grandfather ( or my grandmothers dad) William J. Buehler. So proud of what he did!!!!

[@DestructiveCreativity]

Seriously? That is so cool! Thanks for sharing.

[@iam_khoshimova]

Thank you very much for a video i learned a lot!

[@carlmckrinn1219]

So happy you have a new video!

[@DestructiveCreativity]

Thanks! We took a bit of a break over Christmas, but we should be back to every Wednesday morning now. :)

[@thedadschooler546]

Whoa! That's crazy that it will go back to its original shape from heat. Cool video

[@DestructiveCreativity]

Thanks for watching! Science pretty much is just magic with a few more steps. :)

[@lucid212]

This video helped me a lot in my studying thanks very much!

[@DestructiveCreativity]

Glad it helped!

[@benjaminbutcher]

Happy new year!!!! Okay so to be honest I subscribed because I like you guys and to help the channel. What's so delightful here is that I'm staying subscribed because the science you guys are showing us REALLY COOL. Congrats on 1k subscribers!!!

[@DestructiveCreativity]

Thanks! We are really enjoying having you watch our stuff. ;)

[@GodsWordMadeSimple]

TOTALLY geeking out at this one! These are the things that made me fall in love with science and want to learn more and more and this one, I had actually never heard of!!! I really love when I learn something that I use every day, but never knew about it specifically! Great video!!!

[@IceDragonKing369]

I enjoyed the video, your presentation is well done and your sister's delivery is improving. in this video I found your natural slip about halfway through where you broke the teacher/announcer persona to marvel at just how cool this science is. I realize I may have worded that poorly, it's meant to be a compliment. Weird hypothetical for you. I'm writing a short story about the construction of a droid. would you say the Nitinol would make a good muscle for a robot the memory reaction seems strong but I've not seen it or felt it myself. Either way great job you two. it's so cool you are demonstrating more niche experiments.

[@DestructiveCreativity]

Thanks for the feedback, it is so cool hearing from actually people :) Thanks so much for watching.

[@601AnnA106]

So cool. Wanna experiment with this

[@h7opolo]

Im a huge fan

[@ArikIsHere]

Thanks a lot! Was really interesting

[@iwayamazeki]

Happy New Year! This was a very good topic, and I thought you kept the depth at a good level. Austenite/martensite structures in steel are what lets us harden cutting edges, bearings, etc. May work for a future topic.

[@DestructiveCreativity]

Good point! I did some research into some of the application of that for an episode and it was looking really promising. (especially in blade forging.)

[@iwayamazeki]

@@DestructiveCreativity And I understand that Forged in Fire is hugely popular, so quite a few people will be aware of terms like quenching and tempering, but they may have only a very hazy understanding of what they mean.

[@moomoo3031]

just watched a Mufon video - nitinol was back engineered from material found at the Roswell crash!

[@cbadplayz4093]

Ya great vid btw loved it if I was a teacher I would use this channel as my first choice, keep up the great work guys!

[@DestructiveCreativity]

Thanks! We enjoy what we do!

[@cbadplayz4093]

@@DestructiveCreativity well that’s great if you enjoy it

[@DestructiveCreativity]

Science often looks like magic! What science do you think most looks like magic? (My money is on quantum teleportation)

[@cbadplayz4093]

Ya prob great vid btw

[@LifeMeetLightning]

Electronics! Honestly, electronics is so ingrained in our lives, it hardly feels like magic anymore, but if you step back and just imagine how life must've been before electricity... man, how far we've come.

The roswell ufo technology metal

[@mcgoatavailoa3097]

Yep, and the mass doesn't know this.

[@wooferchewbone6166]

came here to do chem homework, stayed for the whole video

[@Mac-Art]

This was found In 1947 during Roswell ufo crash

[@h7opolo]

6:40 shape-memory loss is not a good reason to abandon the nitinol engine, and it's an inexpensive, reusable material, so, yes, this technology really is being intentionally suppressed. I aim to correct that trend...

[@crabtrap]

in 1947 you could find this stuff in the desert.....of new mexico
