This video explains everything in a practical and an informative way. It's much easier watching this and learning rather than read boring long textbooks trying to imagine everything. Loved it.

The structure that form when steel is heated to 720 C is called austenite and when it is quenched the cristal that form are martensite martensite is the hardest metal structure but it is also fragile. This video is very well done 🙂. I have done my master degree in powder metallurgy, and it is more complicated, however, if you verify your car you will find that many gears in the engine are manufactured using powder metallurgy.
I dont know why someone decided to make an engineering video so perfectly, knowing that it wont have good recenption, but its too helpful for me in 2023 after 2 to 3 decades!!
I watched this video years ago and enjoyed it every bit as much this time as I did back then. You'd be amazed how much you forget from educational material even after a day or two. Never mind several years.
Old engineering videos are soo wonderful!! I mean as the graphics and use of technology has made the process of learning hard. I finally understand the topic.

I, Harry Nguyen, am one of the leading chemists of Harvard University with several PHD degrees. Watching your video, sir, had really brought tears into my oculus. I am feeling an overwhelming excitement through every cell in my body. This video is indeed the 8th wonder of humanity!
An excellent way of storytelling of dry engineering subjects. The persons who are involved know the art of scriptwriting and screenplay. It requires gigantic effort.
my lecturer taught me about materials engineering using old videos similar to this video. I have to admit, learning with old mechanical engineering videos such as "US Auto Industries" and other similar videos is actually easier to understand than today's teaching videos. somehow the method of explanation is more detailed and makes more sense.
I just love these old videos. The producers seemed to actually understand the working principles of things and to be really concerned about making the audience understand it as well.
It's been a year since I took an Engineering Materials class, this video made a big click in my brain finally making some sense of what we were actually talking about in that class.
This video helped me to get the subtle idea of grain and grain boundaries. Very useful video for learning material properties. Love to watch it again and again...Thanks BBC

After watching this video my all doubts about grain, crystal, grain boundaries and recrystallization has been cleared. Thank you very much for this amazing video.
this video explains very well, especially the low carbon steel structure and crystal grains are explained simply, the eutectoid point region is explained beautifully and simply
My area is optics and photonics. I had difficulty understanding the microstructure. This lecture has assisted me in understanding the grain profile in a short time. Great pieces of stuff. Thanks a lot!...
This was beautiful and the narrator's voice was oddly soothing. As a mechanical engineering undergraduate, i have to say that this is pretty informative and easy to remember. Remembering these structures, temperature limits and their properties is a challenging task if you are reading it from a book, but this video makes them so streamlined. Thanks for uploading this.
LOVE that inverted stage microscope, what a beast, and that carbon addition... poof! And the impact tester, funky and dangerous haha. At least that lab coat dude didn't have to lift it above his head like the old Charpy tester at my department! And the graphics are just charming.

@@junaidhussain4781 Not sure I understand that question properly but based on the fact you said a bunch of tests have been performed, you can look at the resulting damage of the material. So the microstructure of a ductile deformation is different to that of a brittle deformation. From this, you can know whether it’s a ceramic or a metal (majority of the time, obviously the ductile to brittle transition in metals needs to be considered as well) and from this you can analyse other material deformations and use your pattern recognition to work out what material it is?

Modern ones are all about fancy sounds and animations. No one cares about the content anymore.

You are totally right
Before we only wanted to learn but now ,we want to excel
