This video is very well done 🙂.

    @@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?

    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.

    Hi, i need help, what if you do varies of test like tensile, hardness and you do not know the material, but when you look at the microscope, how you would identify what identify what type of material it is based on grains.

    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.

    I never knew I needed to know what recrystallization and grain structure were. Also the various machines they use to heat or bend the metal throughout the video are really terrifying.

    My late mother worked in the General Electric metallography debt, and she had some cool pictures from tantalum carbide in a bismuth matrix, to other crystal structures that design students wanted, because they were like art, but for needs. Some clothing has technical pictures in biology and metals for inspiration.
