Understanding Metals

Get access to the extended version of this video on Nebula - nebula.tv/videos/the-efficien...
To be able to use metals effectively in engineering, it's important to have an understanding of how they are structured at the atomic level.
In this video we'll explore metals, their microstructure, and various techniques like grain boundary strengthening, solid solution strengthening, precipitation hardening and work hardening that can be used to improve their properties.
We'll also cover phase diagrams, focusing on the diagram for Iron-Carbon atoms, that shows us the different phases like ferrite, austenite and cementite that can be found in steels for equilibrium conditions.

[@hnrwagner]

As an engineer with many years of experiences in material sciences and a KZbinr which covers mostly metal material models (kzbin.info/www/bejne/p5TGqoR8r66AfK8), I can say you did the impossible. This is a very important but also difficult topic and your 17 min presentation it worth more than most Professors could teach in half a year of lectures, very well done.

no fucking joke, i have this subject now and ortho the book i have has started to make sense, my professor can't seem to explain anything except how basic algebra works and that giga is a million... he also has to write the entire example text word for word from the book... he just copies the book

This is pure art. 1-st semester of material's science couldn't be summarized better.

[@mountcrushmore566]

You could turn a deaf, blind and dumb dog into the greatest physicist of all time. Covering material like this with this level of efficiency, clarity and immersion is nothing short of an exquisite form of art. You, my friend, deserve a lot more credit than you get.

[@CoDFOTIS7]

As a metallurgical and materials engineer, I have to say that your video is a must-watch for someone interested in the field of physical metallurgy. That was a very concise summary of such a broad field of engineering that touched upon all the basics in such a short period of time. I have to admit that I took the same approach of presenting the basics last year, as an introduction to my texture of metallic materials presentation to my MSc. peers, but god I wished I had such great animations. Well done and keep up your terrific work!

[@alphacenter7366]

do you get job with this degree "Material enginnering"?

[@CoDFOTIS7]

Of course you do get to work as a Materials Engineer in various industrial or research positions. The job offers may be less than let's say mechanical or electrical engineering but the market needs metallurgists and materials engineers more than ever on its quest for sustainability.

I learned rural blacksmithing when I was a youth, so it's really neat to see the reasons down to the molecular level the quenching and tempering we did. Based on the last diagram, I guess we were aiming for a mix of austenite and cementite for some things, and ferrite and cementite for others, so interesting!

[@HollywoodF1]

Get a good understanding of all his videos and you’ll have a much easier time understanding and filling in the blanks in engineering school. Unfortunately, most topics are taught in a manner where a concept is introduced and then the entire depth of the topic is discussed before you move on. It’s far better to expose yourself to the breadth of concepts first and drill down after you understand the global framework of concepts.

Reviewing my engineering knowledge throughout those videos is amazing! Sometimes I make a concept more solid, sometimes I actually learn in a deeper way, something I thought it was already learnt.

[@eshh183]

The visualisations! Nearly all the comment's are praising how good your animations are, but still it just doesn't feel enough!! Honestly, the best animations I have ever seen on all of STEM KZbin. Couple that with your to the point, precise and easy to follow naratation, and you got a winner!! Seriously. My favourite physics channel on all KZbin. Please keep up with this GOD DAMN FREAKING AMAZING Stuff!

[@peckdec]

I'm thrilled that you are able to present so much information in such a short time. This is precisely the level of detail I think introductions to subjects should be made. It can often be daunting to pick up a textbook in order to quickly get an idea of the subject because the textbooks often go immediately to the final level of detail without providing any kind of overview first. Here you are teaching the basic ideas of perhaps a whole textbook in one 18 minute video. Keep up your amazing work!

[@jasonwhite2028]

I cant believe how much you cover in this video and the visual examples are excellent, metals and the innumerable combinations and interactions with temperatures and its final crystalline structures as a result will always be beyond me, but you have given me a better understanding of whats actually happening to the alloys you covered then working with them all my adult life, i hope you will cover more in the future. Thank you for your great work.

[@webx135]

The corrosion resistance mechanism is pretty cool. Let me know if I'm wrong when I describe this. Iron oxidizes as we all know in to rust. Rust doesn't repel water especially well, so iron deeper and deeper down continues to oxidize. Chromium still oxidizes as well. However, its oxides are hydrophobic, so only the outermost layer can oxidize, protecting the rest of the metal from oxidation. When you combine iron and chromium, there may be some iron that oxidizes, but because it passes through, it can still oxidize the chromium, creating a waterproof layer that protects both the chromium and iron inside from further oxidation. But IIRC, chromium oxidizes faster, so it creates its protective layer before much of the iron can oxidize in the first place. So it isn't that stainless steel doesn't oxidize, it's that its oxidation state is waterproof. It creates its own waterproof layer.
