Why does every get so jacked about forged parts? What's really going on when we look at the molecular level of different metals when they are being made, used and destroyed? Today on B2B, we're going to find out.

Frizzle is operating on a level I was not prepared for.
-
Coming from a polymer/material scientist, this is a great simplified explanation, love it! Only thing I can knock it for is the use of "silicone" vs "silicon," two VERY different things.
-
Guys, I’m a mechanical engineer at a fully integrated steel mill in Ontario. Real recognizes real and this is some of your best work. Absolutely awesome lecture.
-
the first 2 years of my college life compressed into less that 20 minutes without losing a single bit of understanding on the material science
-
This video hereby confirms the existence of the Jerryverse
-
This is the same reason why diamond is so strong, while also being made of the same material your pencil led is. It's the alignment and structure of the carbon atoms that give the diamond its strength.
-
“While preventing oil from escaping into the combustion chamber” GM Vortec: lmao
-
I am a materials scientist with a PhD. Most YouTube videos you watch these days are haphazardly prepared and are supported by superficial research efforts. This video, although not very deep in content, is absolutely flawless in explaining the engineering principles. I watch Donut as a comedy show but I also learn a great deal about cars etc. Thank you guys for your service to everybody who likes to learn more about engineering.
-
The amount of effort put into this episode was very appreciated. Loved the lesson too, thumbs up as always!
-
Definitely an episode that's deserves to be watched more than once.
-
Loved the Magic Schoolbus throwback!! Tbh really wanting to see pressing force required to squash the piston from the bottom like he did to the billet, but compare all 3
-
Mechanical engineer here, I love that Donut is taking concepts I had to learn in college and making it easy to digest. Materials Science is pretty dope, obviously. Keep it up dudes
-
This dude is the only person I can watch change into random different characters all the time and take anything they’re telling me seriously.
-
The Mr. Frizzle bit had me feeling like I was watching KVIE. Well done.
-
If you look closely at the forged piston at the end when it gets split open, you can see that the grain structure is a little different near the surface of the part. Since it's pressed into a die at high pressure, it forms a sort of crust on the outside that is very strong.
-
I'm in a material science class for my engineering degree right now and this makes more sense than my professor explaining grain structure.
-
JerBear is rapidly approaching James-level entertainment levels while still being the smartest of the hosts. Well done.
-
Awesome job on this video, Donut crew! Thank you for the opportunity to be involved 🤜🤛
-
"As you can see... the main pancake part of the piston is still ok" Lol metallurgy go BRR
-
Awesome job by the editing team this episode’s effects and transitions were really impressive along with the seamless way that clips are stitched together for jerbears characters. Very entertaining and informative at the same time.
