i learn more from this video about metallurgy than 6 months of school when it comes to metallurgy, and the properties of the different alloying component.
Trust you shall read your text books in a new light.
Wow, school short changed you .
It's rare to find a video so thorough when it comes to alloys, thanks
I’m a Metallurgical Technician going to an interview tomorrow morning. This good stuff. I was looking for a review. I’ve only got the one course on Metallurgy they teach in Oregon and three years experience in a Met Lab. It’s been a year and eight months since a large cutback cost me the best job I ever had. This is stuff I’m familiar with, but this video is great. Just what I was looking for. 👍
I hope the interview went well! Did you work in steel in Oregon?
It's amazing how many different variations of steel there is, just by adding different elements in varying amounts and by how it's heated and cooled.
This is the groundwork and fundamental, material principles that determined the innovation and foundation of our civilisation. And here I am, motivated to look into this subject at length solely to make perfect Greatswords that cannot be lifted by normal men or broken/corroded, or legendary style weapons that goes into a culture's mythology they're so awesome/scary.
PICS!!!😎
Simplified and straightforward. Thanks very much
A 100% pearlite structure is at 0.83 carbon. This video takes me back fifty years when I studied the subject.
As someone who knows nothing about Metallurgy, I can tell this video is very informative, but it reminds me of the Retro-Encabulator.
Remarkably informative, concise and well produced video. Thanks!
wow, thank you so much, i am currently studying , i am an apprentice tool maker, and so far the information supplied via my course has been extremely hard to grasp. when you see the graphs and read the words its not enough to understand how to read the graph its self . This video made so much sense. it really made everything i have been reading click into place, especially the graphs.
thanks to this video it all fell into place. thank you so much. i have been struggling to understand this. and now i see how simple it all is. i really appreciate the effort you have made to explain this heat treatment system. thanks again .
@@MetallurgyData awesome. I have subscribed. And I look forward to you up coming videos .
I'll have to go over this one again so I can get it into my memory. I have a test coming up soon. I was a little worried about it , stressing out because I couldn't understand the graphs . But with this video explanation I'm feeling allot more confident .
@Dan Smyth i feel identified by this man
Really great videos . Enjoying your channel. It's a real shame you don't have more views, hopefully people will come. Keep up the good work.
thank you for this!it is very well put together
Great video! Loved the visuals, very easy to follow.
Brilliant video.
Thank you!
Very informative! Excellent graphics! Clear explanation!
Awesome video, I'm subscribing, I can't wait to see what else you have to offer 💪💪
this is the info i have been waiting for , subscribed
Thanks for giving knowledge in metallurgy sir 👍
This is incredibly good! Thanks
Tanks for sharing this knowledge. Tremendous job done by you.
Thank you for giving a valuable information .
Sir thank you so much My all point about Steel cleared.
You made it sound so easy....yet confusing. But i am still gonna subscribe becos you make sense
Thanks for teaching
wonderful video, I have learnt a lot
Thanks for your explanation and it's helpful 👍😀😁
Very informative video. Thanks
thax sir
'' amazing explaination''
Great content! Keep it up!
Sulphur combines with manganese to form MnS (manganese sulphide). This MnS combines and forms slag. It is than removed by de-slagging process thus lowering the content of Sulphur in steel/austenitic manganese steel.

Very much clarity 👍
Excellent information
The best so far
Thanks a lot , great work
Thank you very much.
V clear presentation
Very informative,
Nice video! Interesting
Nice video for training
good information..... thank you....
Wonderful video
please make a video on ultrasonic annealing of metals.
Love this video.
Nice explanation
Leaning casting process 😊
This video is satisfactory for Undergraduate students
Hey Mr. Paguel’s class!!
Great thanks Sir
thanks guys
good informative
Great video
Is there anyway the maker of this video can allow us to download this video as some kind of power point or slides so that we can save it to our computer for future reference? This is extremely valuable information
theres this thing called taking notes, i dont know if you've heard of it before but it works great
Why not take a screenshot for every step in the explanation?
Good informative video - need more like this. However, the background music is distracting and of no value.
i agree, good content but the background music makes it really difficult to concentrate on the information
indeed, the presentation was disturbed by the useless music.
You guys live in the 60's , stop doing that .
Had no problem with the music, I got to understand all the presented information.
Your face is of no value...
Low or slow cooling rate means towards left side or right side of ttt or cct ???
Thanks
good inforamation
Manganese is combined with sulphur to prevent hot shortness???
Pls explain...
If sulphur is allowed to remain in steels, hot shortness results, meaning you would have non-metallic brittle phase between the ductile iron grains...no good. So we add Mn. This now combines with the sulphur, forms MnS which does not form the brittle network at the grain boundaries. Hope this helps.
Hot shortness in kind of innacurate. Hot embrittlement is more accurate. It means growing the temperature at which steels become brittle (eg.: if a steel usually embrittles at -20C, if it has a high sulphur content (~0.5% or more) it could embrittle at -10C). When we add Mn, it forms MnS (in combination with S) and this (partially) eliminates hot embrittlement.
So basically Sulphur is a bad impurity to be in your steel that leads to brittleness especially in low temperature but we can still counter it without trying so hard purifying it by adding Manganese? am I right?
very good video
Nice
Question I have some material with Cr .50 Ni 3.5 and Cu 1.25 but can't find a grade for it anyone know?
delta gamma transition region is not according to standard carbon % please correct that if possible
V nice
can you provide more videos
I am writing a novel where there is a character that can manipulate soil, rock, metal and minerals. So he can basicly alter steel for different purposes. Now things got more complicated than I anticipated.
How goes the novel? Sounds interesting.
@@mattheww9656 didn't get to continue writing on it. Still thinking things play out before sleep every day.
A novel about a metallurgist? 😍
@@krzykris No. It's about a young inexperienced king who wants to make a place where people can follow their dream and escape proverty.
So what's the best steel for a sword? Best combo of hardness edge retention and shock resistance?
Hay en español??
How does the SS retain austenite phase at room temperature when below 723deg austenite does not exist ? Do you mean you heat to above 723deg and quench it to retain its austenite phase ?????
@@awashburn6944 Sir, does that mean (as per the graph) the phases at different temperature, actually refers non alloyed steel ?
But sir I need information about Carburazing process and Austempering process.
There might be a bit on austempering in my heat treatment video
th-cam.com/video/skQRLfU3plM/w-d-xo.html.
What about temperature
This video went from very interesting and understandable to wtf are you talking about
Ha!
i think your doubts would be cleared after watching this video :)

@@arkitkabir5086 Thats actually a pretty great resource, thanks for sharing
@@arkitkabir5086 lol just watched that video previously. Old videos are much better
nice vid. some small "faults". for ex. chromium used in stainless steel? chromium is what makes it stainless steel :) *used in steel to make stainless steel.
That is not a "fault" in any way. In the manufacturing of raw stainless steel Ferro Chromium is often added to the melt in the process. As a rule stainless scrap with approximately the required content for the elevant specification, is used in the charge. As a techno person who worked with many, many specifications including most stainless grades for over four decades I can vouch for much of the info contained herein.
1:07 to 1:58 literally shows most of the definitions 👋
the alloying is just gods version of irl potion brewing

Almost couldnt watch because of the music haha
Who else is here for the welding assignment?
This is the kind of teaching that should be done in a Metallurgical Engineering curriculum, but it's not. Instead they go deeply into dislocation theory and crystallographic transformations in a way that will only be useful in a research position. A Bachelors degree in this field is now useless. Don't even bother.
@@awashburn6944 I'm sure there was more but that is what stands out. Metallurgical engineering turned out to be such a bad choice that I now call it a "non-education for a non-career."
@@awashburn6944 Silly, the reason I left the Rust Belt for Canada was because there were no jobs for me. I did not want to sit out most of my career waiting for it to change so I picked up and left. Simple as that.
@@awashburn6944 I agree. I was very fortunate to learn about phase transformations from the guru, Thaddeus Massalski, during one summer in a class of only 3 students.
@@awashburn6944 Plenty all over the U. S. for the last few years.
skip the first 7 minutes to get to the iron carbon equilibrium diagram
ditch the music otherwise good
No music please.
Music is very loud
Turn down the "background" music please.
background music sucks...
it should not be added during educational videos.
I have no idea wtf is he talking about but it’s better than tiktok anything
would be better without music
If I see this RS means advertisement one more time I'm gonna lose it
Does anyone want to open a Special Issue about any type of Metallurgy in MDPI Metals? Hit me up if you have h index over 10 or 15
He misspelled metallurgy in his powerpoint but I don’t give a fuck, it’s the info I hear.
And mispronounced it as well :-/
Valyrian steel composition was not covered...
@Matthew M lol
Dragon Glass + Steel + Dragon Fire = Valyrian Steel
@@nazmulhaquenishan2591 sounds like a fantasy world version of crucible steel.
"centimetre squared" should be "square centimetre". It means a different thing. The second one is a unit of area. The first one is a unit of length where the number is squared. 2 cm² is not (2 cm)² = 4 cm.
The background music is maddenly distracting,
no
Could do without the music
Autoplay led me here. Idk what TH-cam is trying to tell me.
No need of background music
Stahle….staaaaahle.
He tip toed around the monkey steel since the 1990s ....bad steel and bad industry in the 20th century
Man please next time not add music it's horrible
I stopped just about 2 minutes in to forward and see if the shitty music was gone. Nope. so not watching this. It sounds sort of like a commercial.
Background music annoying as heck
