This was a double feature for me. Listened once while falling asleep and it put me right out (which was the goal). Listened again while fully conscious and found it super informative as a materials engineer. Rare for a podcast to be so good at both of those applications.
How do you actually retain the information? I find myself forgetting basically everything quite quickly. By the next day I totally forget most of the things I watched. I hate it.
Omg the algorithm has blessed me. I downloaded the entire podcasts playlist. I’m a machinist studying to be a materials engineer and this is fucking great stuff. The entire podcast
why didn't you choose mechanical engineering instead? materials engineering is more lab or computery then industrial, which i assume you are aiming to work in, manufacturing?
Im a machinist/ marine diesel mechanic, and wooden boat builder, but i actually started off studying philosophy in college. I have been fascinated by the evolution of technology, especially old technology that is still close to or even surpasses some modern tech. By far one of the most fascinating things is steel. Like, you can make it softer, so that you can cut steel with a piece of itself. Before the invention of fancy pyrometers, you can get pretty accurate changes in hardness by looking at the different colors that steel glows when heated, and those colors are in the visible spectrum of humans!?! In scandinavia and other parts of europe, the "bog iron" just precipitates out of the bog water, so you can develope iron technology witbout wven haveing to develope mining technology. Say you were an iron age peasant, but you were gangster, and you got an iron knife from your dad when he died. If he died in a house fire, the carbon in his body would infuse the surface of the knife with carbon, making the surface case hardened steel, so like the spirit of the ancestors infused your blade and made it better. Im an agnostic, but the usefulness of iron, and how well suited we are to make iron stuff is the thing that makes me question my agnostic beleifs more than anything else, hah, iron is just too convenient.
Really great episode, thank you! It would be fantastic to have a similar overview for aluminium, putting into context the different methods of hardening and strengthening.
Incredibly interesting! The levels of expert knowledge just casually thrown around in this discussion were fantastically enjoyable and informative. I am very much looking forward to watching my way through all of your channel's videos.
Thank you for the depth and breadth of this discussion. For me, conceptualizing the molecular basis for properties in materials helps me as a hobby machinist.
This podcast is absolutely fantastic and I’m so happy to see this. As a graduate student in welding engineering at Ohio state, I would love to see an episode on welding metallurgy of steel and/or other alloy systems. At least one of our professors would likely be happy to come on as a guest as well. This is one of the best efforts I’ve seen at showing how interesting material science and specifically steel can be to students and young professionals.
@@helpimlost137 hooray! I'm so pleased you enjoyed it. Share it around and which Prof should we contact?? Ideally somebody with some personality and story telling ability
@ I’d say Dr. Antonio Ramirez is a good fit. Most of his work has been with all the different types of stainless steels but I know he’s worked with steels similar to the low alloys discussed here, nickel alloys, and more exotic alloy systems. Dr. John Lippold is another one who is very well known in welding engineering and metallurgy though I haven’t personally worked with him. And don’t worry as soon as I got in the grad office I told some students about the channel!
One of the best episodes, not only in Materialism Podcast, but in any podcast I've ever listened to. I love how you think about your students needing a centralized resource for finding a grade. Perhaps the associations should develop some "buying guide" or flowchart, hopefully interactive.
This is the most fascinating podcast I've ever listened to, usually it's just background noise but I was actively listening to every word. Keep up the great work!
I like to think that I know a little bit about the properties and states of steel.. But I also like to be proven wrong at times. For a long while now, I have been searching high and wide for a thorough discussion on carbon steel, with zero luck.. Then this pops up in my feed! Fantastic discussion guys. Thankyou for sharing such valuable information. TU and Sub!
This is a very interesting podcast. I’ve learned a lot. I wish you would do more in depth research related to steel and other metals used in manufacturing processes. Thanks.
@@greglaroche1753 yeah, we try and find the balance between breadth and depth. We are for sure interested in doing some follow-up episodes that go into greater detail
Oh lord! The intro alone earned you a Sub mate. I'm an engineer, and flat out, wouldn't pretend to know vast expanse that is the knowledge bank involved with steel.
I'm no material scientist (in fact my degree is in sociology), but I have had a fascination with the science of steel for a long time and have done a lot of reading and research on my own. Some of the best resources I've found have been the late Dr. Thomas Eager's lectures posted here on UA-cam as well as the book 'Knife Engineering' by Dr. Larrin Thomas. The latter is hyper specialized towards the blademaking hobby (where my interest stems from) but has some fantastic content and is very technical. Also borrowing the textbook 'Engineering Materials 2' by Michael F. Ashby from a friend of mine helped build a great foundation.
Tom Eagar was both a great professor and a very approachable resource at MIT. His passing was something I found (to my distress) while searching for information on welding. I'll check out his videos that you've mentioned, thanks for that.
Hi Taylor, The discussion on steel composition is fascinating. I have some questions but first a caveat: I'm definitely no expert so I'm likely wording this wrong. Questions: "killed steel" goes through a deoxidation process for the purpose of obtaining a tighter lattice/grain structure. It's my understanding that the final composition includes Iron (Fe), Carbon (C), Manganese(Mn), Silicon (Si), Phosphorus (P), Sulfur (S), (Oxygen (O)
Like alot of others the algorithm brought me here, I hve no prior knowledge of or work with steel....but I figured ive been led here to learn ..'ll try my best to comprehend and learn ... Thankyou
I was user of various metals for fabricating parts, from those materials. So I was aware wide array of metals. Even in just carbon steels, without getting into other steels such as large selection of stainless steels. Also aware of the microstructures, and the corresponding heat treatments, when applicable.
"Don't touch that please, your primitive intellect wouldn't understand alloys and compositions and things with... molecular structures." -Ash This is great stuff. Thank you.
everyone in this comment section is like: "as an engineer in nuclear material rocket surgery, this was really informative" so i'd like to add my own. As a concept artist painting trees for animation and games, this was super fascinating T_T
That's interesting that you can put a tiny amount of aluminum in for corrosion resistance. Did you know if you try putting a lot in for reducing weight it gets super brittle?
@@MrBrew4321 without checking I can't say, but my intuition tells me you're just going to form intermetallics that will ultimately make it more brittle
Which steel would be best (better than the typical 1008 used) for making magnetic motors for woofers? Is highly pure iron available in say 6-8 inch diameter rod?
5 minutes in, this is a waste of time without graphics! How are you talking about crystalline structure without pictures? I understand this was originally a podcast, but when you put it on youtube you should have added diagrams.
I'm gonna say the volume is way too low. Turn it up before uploading it. I had youtube at 100% vol and windows at 100% and i could barely hear it compared to most ideos which i listen at 20% vol in youtube and windows at 30% vol
@@TaylorSparks yup. And the history of steel is another way to go at it as well. English steel in the late 1700 to silver steel into an explosion of alloys for various uses. Love steel and iron.
@@ryanbeard1119 always tricky to ride the line between depth and breadth. We want to make it accessible to everybody while satisfying the experts. We will probably do a follow-up episode where we can go into greater detail
@TaylorSparks ok, can you explain, I though H C s let's say 1.00 percent carbon, not molar or molecule number, but I thought you said the number was way lower, so does that mean carbons weight is way greater than iron molecule?
The audio levels are totally out of whack. Please do a bit of research on this and how to mix and record audio for podcasts. It is something that requires a bit of knowledge but it’s not that complex if you follow some simple rules
@@TaylorSparks love the show, I listened to this episode on Apple Podcasts where I think they do some audio processing (compression & limiting) on their servers when you upload. I’m glad UA-cam recommended this to me
What's with this trend of insulting viewers (or potential viewers)?? Any machinist, mechanical engineer, metallurgist, or frankly, most knifemakers, know all of this stuff. They teach it - all of it - in FAmous Engineers School, did you know that? Stop being pretentious and just, you know, scattershot insulting.
I was surprised by the discussion. Lots of talk about specific processes, named but not explained. For me, the most important fact about steel is that it is a naturally composite material and the mix of phases depends sensitively on processing. I decided not to subscribe.
If you deleted the first 35 seconds of the video I wouldn't be confused on if I clicked on a serious video or an AI generated flop. Anyways. Sadly podcasts aren't my thing, I like educational videos like how Fermilab and TheScienceAsylum do.
Hobbyist learning how to TIG. Friend/instructor got into this a little, searching for more led me here. Tried basic welds on aluminum and some steel coupons, such different interesting properties. Would be interesting to hear details about applications such as what happened at Blue Mesa Reservoir CO. Casey Jones covered the the T-1 steel story but more from an engineering standpoint.
