#like y'all wouldn't believe what amounts of bullshit you could sabotage with very very small differences in what types of welding or metals

not aro culture related but UR AN ENGINEER? THATS SO FUCKING COOLLLLLLL AAAAAA

[empty paragraph in case tumblr eats it]

👉👈

i’m not technically an engineer yet since i’m currently closing out my third year of undergrad, but i’m currently set to graduate with a B.S. in Materials Science and Engineering in spring of next year! I will basically do a lot of engineering of material properties / processes to achieve those properties, with a specialization in metallurgy (the study of metals) and I’m currently adding a minor in Nuclear Materials :)

#not aro culture #mod kee #👉👈 #yeah so y'all might see why i'm so uh. rules and tag oriented #if i don't know what things are and check the rules for them i could aboslutely do Not Good Things #like y'all wouldn't believe what amounts of bullshit you could sabotage with very very small differences in what types of welding or metals #ooh and some fun facts for y'all: there is a type of welding called explosion welding #it is exactly as it sounds. you make a (small) boom and slam the two materials into each other very carefully #kinda has a distinct wavy interface look between the two metals #uhhh one thing that i'm very used to but y'all might not know is that there is often more than one solid phase possible in pretty much any n #non polymeric material and that's only me saying it cause i'm shaky about what's considered solid phases in polymers #also never put gold coating on a silver ring or smth someone mentioned that to me once and the phase diagram is literally totally miscible #aka silver and gold will completely diffuse into each other in time and you'll just have a silver ring with sparse amounts of gold in it tha #on the other hand a true pure gold ring is p a bad investment the added impurities in gold for jewelry are to improve the quality not cheape #pure gold is kinda shitty for the purpose of holding shape #we usually add impurities to give it a more rigid structure that isn't gonna deform the first time you like... accidentally have life happen #ooh also impurity is a neutral word in my field #like sulfur in metalworking tends to be Very Bad because it changes a WHOLE lot of properties in very small amounts (like. it straight up re #reverses the flow of liquid metal in welding) #but like semiconductors wouldnt do shit without added impurities #silicon is just a really really good material to use with tiny amounts of added impurities #uhh i'm p rambling a lot but!!! i like my field!!! #also rip me all the time because metals and ceramics have crystal structures so i do a lot of searches relating to cyrstallography #can you guess what google thinks i want ads for. because i didn't #getting weird healing crystal ads is not an anticipated outcome of an engineering major and yet.like no budy i just needed to know what the #lattice constant of a particular quartz phase is to do some estimates #or like. last night i was checking out the phase diagram of hmm i think titanium and aluminum so i could double check that they had intermet #intermetallic compounds (sorry tags were eaten) #and BOY do they. kinda want to see if any of my profs can tell me more about why that's a Thing #disimilar metals really like to form absolutely useless and awful IMCs when you weld them
