Superalloy - A Material That SHOULDN'T HAVE BEEN CREATED! 

Interesting

Ti-Al

Was it MTU Aero Engines? I worked there :)

Was it inconel or something exotic? My dad used to work at Rolls Royce and they started doing single-crystal titanium turbine blades in the 80s or early 90s. The previous stage was getting the crystals to grow so that they were orientated along the length of the blade.

I have also heard of this! Seems like a lot of materials and a lot of time to fashion and create such a scientific war machine, but it also makes me wonder how the Germans got the time and materials beings it was the ending of the war!

Much better than what Nile Red has turned into. I wouldn't even call him a scientist or chemist anymore. More of a sh*t posting channel that lost its way. Thank God for Thoisoi2!

Thoisoi, applied science and Nilered are top tier science channels, wish Nile still made full videos tho

@@NotaWrxTrek Nile is more of a chemist lab science

100% hes got a cool science channel

Both Thoisoi and Nile are great but Nile still doesn't upload

Good luck with that. Most of the info on that system of manufacturing is still a very closely guarded secret

demonstrating that at home is very unlikely, you need very specialized machines. single crystal alloys arent necessarily hard to do as the alloy itself but rather creating the environment to cause the alloy to form a mono crystal is the issue.

@@ph11p3540 I hate trade secrets so much lol.

@@ph11p3540 Other than the black magic metallurgy the process for single crystal growth is simple enough in concept, it only gets fiendishly complex when talking about how you actually implement it. When the liquid metal alloy solidifies it will tend to solidify along an existing crystal. This means if you have the mold cavity tightly thermally controlled you can use a corkscrew shaped passage in the mold to start the cooling process. Before the corkscrew as the metal solidifies it forms many crystals as you'd expect but as it's solidifying up the corkscrew the geometry of it favors the crystal on the inside edge so by the end of the corkscrew that innermost grain has overtaken the others to form a single crystal.The hard part of implementing this is dealing with the precise thermal gradients, temperature control, vacuum casting, etc to actually keep the solidification process consistently along a single crystal growth boundary. Bismuth is pretty good about growing large crystals, it might potentially work to show that corkscrew method working in bismuth although I don't know if there's an easy way to show grain boundaries in a solid piece of bismuth like you can with etching steel. It might be possible to make a plaster mold and demonstrate the difference between the corkscrew passage and no corkscrew on the crystal growth as an amateur. For anyone interested in the topic there's this video that gives a bit of the history of turbine blade manufacturing, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1zHSK-Nlaz0.html and an excellent video by AgentJayZ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jCb6-LGfeHg.html

@@AndrewMerts 6:12am how would have know the metals cause such reactions. 😊

I remember my excitement as a high school student when I visited an engineering metals shop and was given a sample of an inconel alloy. At one point I put it in a vise and tried to hacksaw a piece off....and tried is the word for it all right... ;^[}

Start by investigating what your real name is.

used to work for PW ;-)

And what are these alloys?(and what are the recipes?(and what are the exact ratios?))

@@magicsasafras3414 don’t think I can tell you that hahahaha

i'll let periodic videos, nile red/blue and that bowtie guy know they need to up their game! 😃

Might be some temperatures and/or pressures where that changes, but yeah, for shirt-sleeve conditions titanium reduces aluminum, rather than the other way around.

@@awashburn6944 I guess I'm thinking that most metals are not used at temperatures where their young's moduli start to deviate much from their room-temp value, but you've got a good point for high-temp alloys.

You've sent me down a rabbit hole Electron beam welding sounds like black magic to my tig welding ass

@@embersaffron5522 lmao, I ended up leaving that job before I got trained (problems on their end) But I got to tool around with the machines, and yeah, they are nuts. They operate in high vacuum, so the roughing pump was a 10" roots screw blower, and the main pump was an oil diffusion pump. It's as high a vacuum as you can get without lab equipment. The beam would collide with the air Everything is done with rotation and oscillating tables, as the beam is fixed like a lightsaber. You're looking through basically a rifle scope mounted coaxial to the beam. The beam is shaped with magnetic fields and can be a fixed point, or made to spin in a circle, ellipse or a line. The tracer power to sight in is enough to etch material. Cranked up, we had a 4" round billet of titanium they used as a focus blank and it looked like a church candle 🕯 My favorite part was that it made metal vapor deposits all over the inside of the chamber. Even the light bulbs were mirrors.... The wrong way (crunchy outside, all the light reflected inwards) The scope had a piece of quartz on a slide so you could keep a clean section on the part

Thats absoutly incredible. I know a bit about electron beams on liek the sterilization and medical side. But to pump enough power to weld metal is so cool. Did they ever show off with ot to the newbie or anything?@@seldoon_nemar

I certainly wouldn't carry it that way, handguns should always be carried with some kind of trigger protection.

@@logicplague2077 I can see how you would say that, but the belt covers the trigger and it's more secure than the expensive holster I bought for it, and other guns I've been carrying daily over the last 35 years, this one for 17. 👍

@@bendeleted9155 Fair enough, as long as it has something.

? What pistol is this? Not that I need an excuse to blow even more money on my firearm collection....

Strange how primative ape persons got lucky like that.

@@johndelong5574 this is a chemistry channel, put your racism away

@@snakewithapen5489 Your virtue is duly noted.By the way, what race are apes?

What's the pay range of said job and how much extra training over welder?

Some more exciting than others, avoid copper.

I appreciate your detailed answers. Do you know anything about DU depleted uranium ordnance?

you'd think they used a magnetic separator... Inconel isn't very magnetic

Not as bad as Isambard Kingdom.

@@trespire Kingdom was Brunel's mother's maiden name. Bessemer was a famous metallurgist (sorry if you knew that), Pfeil senior was an accountant.

I've heard a story that somehow some plant-touring Russian scientists stoled the material composition of that Inconel material by intentionally walking to the metal shavings at a lathe when a sample was being prepared for testing and then analyzed the shavings when they returned home.

@@davidschwartz5127 That's not a story. That is a well established trick to steal chips / dust / gold. One way to prevent such industrial espionage is to provide "safety shoes" to visiting guests.

@@trespire Not as good, I say!

Hey, that’s chemistry/metallurgy. You can try to estimate the properties of a metal alloy, but you can’t be completely certain until you’ve actually made it

Termites be different over there...

@@guarami1 😁

@@guarami1 Hey. Don't make fun of my Canadian accent lmfao.

9/11 was the best example of a thermite reaction.

no point, he didn't get anywhere close to making inconel lol at least he apologized to materials scientists, it's a big understatement that it's more complicated. As disappointing as it is for a youtube video, you can't make superalloys in your backyard. Unless you spent millions of dollars equipping your backyard..

Inconel and other superalloys are not suitable for making knifes because they are too viscous and don't get sharp.

@@Thoisoi2 I see. Another elements that I thought are plates to cook fast food, pots and trays for oven. Do you think Inconel would be good for those things that are used in direct contact with flame? Thank you very much for your answer. 😀👍

@@FedeG86 Kitchen stainless steel is good enough and much more cheaper than superalloys. They are used primarily in special conditions.

I´m surprised that out of all the comments here, Thoisoi chose the one about kitchen utensils to respond to :D

how did you sharpen it?

He never mentioned strongest alloy. I think he mentioned it as heat resistive alloy

@@bapibarman7484 No im saying he should make a video on maraging steels aswell.

this super alloy is pretty close to it anyways

The blades of the rotors are in the same direction, the stator blades in-between the rotor blades are in the other direction. The stator blades were not shown in his animation.

Apparently the little known Eurasian termite has great exothermic potential!

it is thermite not termite.
