Thanks for watching! Remember you can catch the extended version of this video over on Nebula - nebula.tv/videos/the-efficient-engineer-understanding-metals-extended-version. Leave a comment to let me know which topics you'd like to see next! :)
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.
@@hewaadamini8388 These comments that say a RUclips video taught them more than X years of college or covered 90% of their degree are way too hyperbolic. It would be nice if we could learn 4+ years worth of material in 18 minutes, but in reality that simply cannot happen, no matter how good the video is.
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.
As an engineer with many years of experiences in material sciences and a RUclipsr which covers mostly metal material models (ruclips.net/video/qccyQFzIMFM/видео.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.
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
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!
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.
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.
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.
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!
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 RUclips. 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 RUclips. 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.
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!
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.
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...
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 ❤️
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 🤯
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.
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'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!
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 RUclips. Greetings from Argentina!
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!!!
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.
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.
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
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 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!
Very good! In 7:15 It's important to control the grain size by considering the solidification time and additive that is used in the solidification process. Additives such as TiBr2 can be used to refine the grain size. CMIIW🙏😇
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.
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.
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!
This tutorial is a piece of art :D how can someone explain such complex topics so easily? I wish my teachers could do the same. I can't thank you enough for making this type of content. Helped me, and hopefully several others, a lot.
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.
You have made it possible to understand that b/c the carbon atom is smaller than the iron atom...I can see where the carbon atom fits in. This is huge...Thank you so so much. This helps my understanding of metals. I know that the stainless steel family warps so much from welding. This has to be b/c the grains of the chrome & nickle are so close together. The heat from a weld has a hard time "leaving". Take aluminum...the heat from a weld travels away from the heated area fast (b/c) the alum. grains are not as close together. Still, with alum there can be warping, have to use restrictive heat techniques. The carbon steel group...about inbetween s/s & alum. It warps if restrictive steps are not taken. Not as much warping as s/s. Great pics of what you explain...Thank you, Pete
Have to say these videos are the best tutorial videos in engineering. I had the same motivation to create similar videos myself last year but seems unable to create such beautiful videos as these. A few thoughts in my mind before I watch all the videos: 1. Thermodynamics and heat transfer also interesting and fundamental in engineering. (The physics of heat transfer, conduction,radiation. What is Carnot cycle, etc. 2. Fluid mechanics may add dimensionless analysis. 3. General introduction of Fracture mechanics. Again, thank you for your awesome work!
RUclips 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.
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 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.
Thanq u thanq u thanq u so much to all the persons involved with this channel.I can now basically understand many things only for this channel.thanq u efficient engineer.. one day i will also become an engineer inshallah whatever it takes
Brass mostly sucks to machine. If you're just flycutting or doing lathe stuff it's like butter, but if you have to drill or grind it, oh my God it can be a nightmare. It heats up so fast and expands so keeping tolerance can be tricky, it isn't magnetic so you can't slap it on a grinder and have to set it up in a little vise and even then you need to keep it super cool, it gums up like aluminum on drills and grinding wheels But yeah if you're just profiling or milling it's pretty nice. That is often not the case though in my experience. I guess i would say Brass is a fairly deceptive metal when it comes to machining. You'd think it'd be super duper easy, but it can really kick you in the nuts. By the way amazing video :)
I wish I had found this video when I was in college. I'd have definitely aced my Materials Science paper. Huge respect to the creators for making such high-quality content.
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 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!
Without people like you RUclips would be useless. Although English is not my native language, I understood you. It shows that, good visualization is important in engineering lessons.
so interesting, im a blacksmith and it really helps to me to make sense of all the info out there. message is clear and informative. well done, definitely going top sub.
wowzer.. i am amazed at how much knowledge u can impart within 17mins. i did a detailed course in coursera on materials and struggled to understand.. your video just summed up the logic behind metals structure and behaviour. thanks..
A very good summarize of materials engineering, I being a student of Visvesvaraya National institute of technology, Nagpur, India could very well relate to it ..
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 like such a kind of video, very short, very informative, very clear English language, and supported by amazing animation.
This channel is so underrated. Thankyou so much for the awesome videos.

I just want to say thank you for creating these videos, the quality is amazing!
Your visual aids are ridiculously high quality and really aid comprehension!
wowzer.. i am amazed at how much knowledge u can impart within 17mins. i did a detailed course in coursera on materials and struggled to understand.. your video just summed up the logic behind metals structure and behaviour. thanks..
A very good summarize of materials engineering, I being a student of Visvesvaraya National institute of technology, Nagpur, India could very well relate to it ..
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.
Heartful of thanks for your effort and contribution to the Engineering community
The way to disintegrate and explain is just amazing.🙏🏻
