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.

Thank you very much Really Appreciate ,
Even the university or ant technical institution doesn't teaches like the way you have tought.
Thank you again.
Please I request you. Make a video on other types of materials also like composite, polymers and ceramics...plzzz Request to u
Congrats you just summed up 90% of my Metallurgical Engineering degree in 17:57
These comments are amazing on how this video condenses the topic. I’m here learning out of curiosity not as an engineer.
@@DeathValleyDazedYou gotta rember this is just a very brief overview. There are very complicated formulas associated with this topic.
Incredible. Such good visualizations too!
Useful info, well explained and mpressive animations. Thanks a lot
love your channel!
Nerdgasm!
Damn so this means I can't listen to this in the background.
I got 100/100 (A+) in my Strength of Materials course last semester because of your videos and perfect visuals. Thank you ❤️
That's amazing, well done!
قطاعة 😂
Unfortunately, we were not that lucky at our university times because this channel didn't exist at that time. But still we take help from this channel to clear our concepts.
I got Nobel prize in Chemistry last year because of your videos and perfect visuals. Thank you!
@@MrAlRats lol
3 years of lazy studdying different aspects of material in 17 min and 57 sec.
That is superb.
Priceless video.
Basically just taught us 1st year engineering in 17 minutes...
@@Johnconno Haha I wish... does a good job of summarising the 1st year materials module though.
i wouldn't go that far. Maybe materials 101 class. Definitely a great presentation though.
So do I
So basically you didn't listen in 1st year engineering
That's a stretch, more like a good intro to materials science
This is pure art. 1-st semester of material's science couldn't be summarized better.
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.
As an engineer with many years of experiences in material sciences and a UA-camr which covers mostly metal material models (ua-cam.com/video/qccyQFzIMFM/v-deo.html), 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.
incredible
Agreed!
with a doctor watching this it made me worry I wasn't going to understand a single thing
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
Agree, we studied all this almost in one semester.
I'm 15 and still understand everything he says. Mad respect man. Keep the good work up.
Bless your brain dude.
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.
im 9 and i understood all
I'm a mechanical engineer and I don't understand all.😭
Tbf this subject doesn't have any advanced concept
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!
do you get job with this degree "Material enginnering"?
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.

Any advice for a freshman engineer?
The quality of this is off the charts 💪🔥
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!
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.
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!
UA-cam recommended this video to me and I am amazed with the quality and clarity of every video on this channel. It must be one of the best content for mechanical engineers, both as students and professionals.
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.
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 UA-cam.
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 UA-cam. Please keep up with this GOD DAMN FREAKING AMAZING Stuff!
Mechanical engineering is not about studying theories and summing up some numericals....it's totally imagination...and your animations prove it beautifully ♥...thanks a lot and keep making vedio🔥
I have never seen this type of crystal clear explanation with HD visuals that make us addictive to learn!!! Hats off to the creator who made extreme efforts for making these videos. Soon this channel will cross above 1 Million subscribers.
Thank you so much for this video. You refresh my memory and make things so clear with the animations. Love this channel. One of the best engineering channels on UA-cam. Greetings from Argentina!
I have my first year exam on structures and materials in about two hours and your channel has helped so much. This is basically a full term's worth of Materials lectures in 17 minutes so thanks!
I am studying for my ANST Level 3 certification (for nondestructive testing) and need to know the basics of metal formation and processing for my exam. These videos are absolutely perfect. They cover exactly what is required for the test but are so much more digestible than pages of dry text. Thank you- keep up the good work!!!
Great work as usual! Having these videos for free is incredible. I appreciate all the hard work put into the channel.
It amazes me that we live in a time where quality content like this is available for free. Thank you so much for your generosity! This sums up many of the highlights from the first two months of materials science on DTU, Copenhagen. That did it, I am now (finally) heading over to Nebula...
A full semester course on Material Science in 17mins, this is incredible.
Incredible amount of information in 17 minutes. Amazing! Great job.
This Channel is Perfect Example of Quality>Quantity! ❤️
I'm so excited to watch this video! Keep up the great work!!
Great work man, I'm amazed of how fast I can understand a topic when watching your videos. Id love to see a video about soils mechanics.
This is grandmaster level of animation, plus it was my entire engineering matetials course in one video. Hatsoff to you Sir!
Wow, the explanation is so clearly, and always in sync with the visuals!
This is the sort of video that makes UA-cam amazing. That was so succinctly presented. Well done and thank you!
I have been following your videos almost regularly. These videos are indeed a masterpiece.
As a Chemist, I have never seen a better and simpler explanation of the unit cell, phase diagrams and the reason why impurities may strengthen materials. This was explained way better than in university 🤯
So comprehensive.... Every time! 💯
The visuals are amazing as well and helps a lot.
I took material science in college and had trouble with the material. Your video helped me understand the topics that I had trouble with. This is amazing, you are an incredible person!
This came up in my algorithm and was absolutely fascinated the whole time. Amazing video, subscribed.
I just want to say thank you for creating these videos, the quality is amazing!
I am a mechanical engineering student at Mediterranean College in Athens, Greece. This channel has nearly everything we studied in three courses during the entire 2nd year. If those who are reading this are seeking some materials to self-study engineering, I highly encourage you to watch all these videos and learn from them, you will basically get the same knowledge I did this year at college as a full-time student.
Always so beautifuly, concisely, and perfectly visualized and summarized. Thank you so much
Gonna add my two cents to these positive comments, that I absolutely agree with. Amazing content and never failing to condense the information just to the right level and presenting it flawlessly, thanks mate ❤️
I have been nerding out on the properties of metals for a couple years now due to my interest in knives. In all the research I have done on the properties of metals just one video here really cleared up a lot of misunderstandings that I've had. Thank you for creating this and posting it.
I'm a big fan of yours, but this is just overwhelming. This video sums up perfectly an entire academic course, about 40 hours long, in less than 20 minutes. Perfect execution! Thanks for helping me become an engineer!
Amazing video, answered so many questions! And the quality is incredible!
Love this video a lot! Would love to see you do the videos on the other 3 categories of engineering materials especially polymers!
I hardly comment on tutorial videos. but this video is too good for me not to thank you from the bottom of my heart. I really like the incorporation of visuals which most tutorials don't have.
Incredible as always!
What I have failed to understand in my classroom, I have learn it here!
I just got my master degree in Materials Engineering Few weeks ago. Your videos are amazing and got me addicted, keep up the good work :)
Thank you! And congrats on the degree!
@@TheEfficientEngineer what software do you use for making animations?
Rarely does one find such a well made video on youtube. Understandably most things are only skimmed over but it's all true and in accordance with what's taught at a university.
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.
I studied Semiconductors in college, I've always had some confusion about how typical metals like iron work. What a delight to watch this. Pretty sweet. Subscribed immediately.
It was my most difficult unit. Thank you for your good influence. It always really helps a lot. I look forward to your kind cooperation.
so far the most accurate contribution to the topic that i have ever seen on youtube
Your visual aids are ridiculously high quality and really aid comprehension!
Remember myself trying to learn the whole Fe phase diagram back in University...If you had this channel then I would have passed the the course way easier. You taught in 17 mins what the professor was trying to teach us in a whole semester...I salute you sir
He just explained what I took in microstructure of Materials for 4 months in 17 minutes. What a great great video! You are a lifesaver, thank you!
I just started my material properties class and this is extremely helpful. Thank you very much!
Before I watch it, I already know that this is the best video on UA-cam
This channel is so underrated. Thankyou so much for the awesome videos.
Wow, just wow. Can not believe a tremendously high-quality video about such a hard topic exists. I'm studying this stuff in my masters degree, and you did a great job explaining everything in a clear yet detailed way 👏🏻
Just sitting here watching what is explained in 17 minutes. Whoever didn't attend mechanical engineering college won't appreciate how much is actually explained this would take your average professor entire year. God bless you
I have been asked to teach chemistry and material science at a university and I am going show this video as an introduction to the course topics!
Very well done,and easy to follow.
I absolutely loved this video and found it so so valuable. I've recently become interested in material science and this was the perfect video to clear up some confusion I had around metals! Thank you! Will we be getting similar videos for the other three types of material?
Man, your every video is like the best contribution to engineers all over the world. I'm not even a student any more, been in the industry for several years, however I still come back and watch your videos to refresh my memory and they always amaze me. We are extremely grateful to you sir!
I just subscribed to your Nebula channel, just to support you sir. Thanks once again
Wow, your videos are EXACTLY what I've needed to review and refresh myself on various manufacturing topics! After several months of unemployment, I just started a new job as a manufacturing QA/QC inspector. The speed of the presentations is perfect! (Those super-brains can just crank it up if need be.) Plus, the visuals are spectacular!
Love the timing and visuals!
Great work, nice explanations & illustrations :) very high quality content as usual
Why has this 18 minute video taught me more as well as making more concepts I already was familiar with 'click' than my whole Engineering Material Science module from first year, which was a full year module.
Great work with very simple and efficient way, please keep doing this great effort.
I am amazed at how well this is explained and summarized. Lots of good information in 18 minutes! What is left to do for the intro to materials instructor now?
OMG!!! this is pure gold. One of the finest explanation I've ever heard........
You are literally doing the work of Gods. Hats off to you man.
Great script, narration, and visuals. I have only a casual interest in this topic, but your talk was fascinating. 10/10.
Absolutely fantastic video. Love metallurgy. Thanks for dropping that.
Learnt many concepts from this video. Thanks for upload!
Thanks! Great great quality. I would love sooo much a video like this about Ceramics.
The quality of video and explanation are perfect.
Excellent video, thank you! I've waited for a long time to get a good lesson like this!
Huge Thanks for your videos, I’am facing a colleague class called “Fundamentals of Properties of Materials” and your videos have been helping me a lot.
i cant explain how grateful i am for your videos. thank you a lot for the content and for the videos. pleaseeeeee continue
i love this and really help me understanding some things that a i cant catch at school
Please keep updating your playlist 🙏
That is how I keep myself organized in UA-cam, thank you for your videos 😀
Guys, I want to congratulate you for creating this curious, interesting and useful content. Keep it going, we all love you
You really do live up to your name. I cant imagine how a better job of teaching is possible. Thanks
Thank you for make these videos
You are the reason I got interested in mechanical engineering and I love it
I have my Advanced Material Science exam in two weeks and now I'm not afraid of it anymore. Thank you so much, you have probably just saved my degree.
Simply amazing ! Keep doing good work.
Guys this is incredible! You are making my life easier! I feel super confident about this topic now ♡.THANK YOU!
Great work ! This video is very helpful for me to explain materials properties and treatment process to my customers. Your effort is appreciated.
I like such a kind of video, very short, very informative, very clear English language, and supported by amazing animation.
This is a beautiful, well-ordered and intelligent presentation. Thank you for making it!
Thank you so much for all of your videos, they really are wonderful !
Incredibly informative. So well done. Very impressed.
This is just amazing. Well done!
A lucid explanation with perfect visual representation 👍
Simply spectacular! Great job!
This was so helpful! This is the future of education! Thank you!
Very cool. I have a buddy in metallurgy at our workplace and he's helping me get into that position. He's encouraging me to watch videos about metals to get a background understanding and this video is very informative.
Thank you for this! I'm a blacksmithing student and a bit of a nerd, so I had a decent grasp of most of this already, but this is very well illustrated and explains it perfectly!
Perfect video. Waiting for one about polymers. Keep up with the good work!
As material Engineer,
These videos are definitely recommended for beginner want to learn about Materials.
