Episode 95: You Don't Know Anything About Steel

[@bobopokomono-nu3gv]

the internet may have been a bad idea, but the marriage of science and youtube makes up for everything. thanks, i learner a lot!

[@August._b]

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.

[@TaylorSparks]

@@August._b yassss. Glad to help with sleep and knowledge :)

[@dianapennepacker6854]

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.

[@TaylorSparks]

@@dianapennepacker6854 super frustrating for sure. Notes and discussion really help

[@gearhead8989]

I am currently in the first stage of this process and just saved it to my fabrication playlist so I can listen to it fully at work tomorrow. 😂

[@cammccauley]

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

[@TaylorSparks]

@@cammccauley heck yeah!!

[@smolcryingpepo]

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?

I don’t know why the algorithm blessed me with this today but I am very thankful

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.

[@TaylorSparks]

@@bondvagabond42 hahaha. I love this whole comment. Spoken like a philosophist!

[@helpimlost137]

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.

[@TaylorSparks]

@@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

[@helpimlost137]

@ 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!

[@raayonaim]

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.

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!

[@wspad2136]

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)

@@gasolinelollipop good idea

[@preauxtip]

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 KZbin 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.

[@davidg3944]

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.

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?

[@TaylorSparks]

@@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

[@gustavderkits8433]

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.
