for the cry of indium metal.
I came here just from searching to hear the tin cry, but this video was so good I watched the whole thing instead
I provide a similar sentiment.
same
The awkward side eye at the end was my favorite part 🤣 Great presentation, I learned a lot 😊
Good you learned.
Very intuitive explanation of what twinning is and how it works. Exactly what I was looking for. Nice demonstration, too! I would have liked to see a close-up of the tin pieces though. Thank you for making this!
Quality video. I know nothing about the metallurgical sciences. Like others, I came here to hear tin cry, but instead, stayed to the end of the video. Even after hearing tin cry in the middle.
Well done.
I came to listen just tin cry, but the explanation was so great I saw entire video
Pleased you like it.
This is so good, I didn't know twinning and slip can compete on the same material at different temperature.
Two years down the line and this video is still useful. I learned something today. :)
Thanks!
yeah , keep learning bro
thank you for all of your amazing videos!!! they help a lot!!! and i can tell you are a great great great teacher/lecturer!
Excellent video, very helpful for understanding twinning
beautiful video
very helpful! you saved my lab report!
Excellet video !!! Keep up the good work !!!
Thank you! That was really educational. Cheers from Argentina.
Thank you
That's one very great illustration. Thanks for the video 👍
Glad you like it
thanks for making this type of video
great video
Nice presentation. Thanks
Thank you ma'am
Wonderful explanation 😃
Glad you liked it
Excellent demonstration on tin cry. (A professor in materials in Canada)
Thank you.
this is very useful for me
Nice demonstration!
Glad you liked it!
So much metallurgy science in less than 4 minutes!
Indeed.
So bending the cold tin faster/harder produces dislocation rather than twinning? How about slow easy bending of the warm one?
If only my teachers were like this
Do nice to see experıment , ı never ımage ın real life this cass.
Thanks from Turkey 🇹🇷🇹🇷
nice
Thanks
So Tin cry sounds a lot like the noise made by most (almost all if I'm not mistaken) crunchy foods. This would mean that they must be hitting the same "notes". Is there some reason why they should have the same frequency distribution?
I have no idea or proof that the character of the noise is the same.
@bhadeshia123 Okay, so when i break bread or other crunchy (brittle) foods, I get a similar sound. For the foods, we can see that this is related to fracture since the components break apart. My first instinct was to assume that something similar is happening here. I found a youtube video "ua-cam.com/video/rXV5tfDJsH8/v-deo.html" for this. First, do you agree with the premise? If so, then why isn't that "crackling" noise associated with microfracture in tin? To elaborate, there could be twining happening in the material, but parallelly there could be microfracture, and it's the microfracture that generates this characteristic "crackling" sound. I'm of course assuming that there is no twinning in food and other edibles.
PS:- When you reply, please use the @ handle, that way it'll come up in my notifications (At least I think that's how it works).
I thought my playback speed is high
Same here. As I age, it is harder for me to understand fast speakers and young people keep speaking faster. Take this into consideration speakers. A great, informative video.
.
bro, play it at 0.75 speed.
It is all relative.
who else cramming rn
What does "cramming m" mean?
Cramming means last minute study and trying to consume as much information as possible in a short period of time.
I was cramming for my metallurgical systems exam.
shouldn't you be wearing a lab coat, lady??
