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

[@Paddydapro]

I did a guided tour at a german turbine manufacturer and they told me the turbine blades are made out of monocrystalline material and they use a casting technique with a crystal starter to get a single crystal. Machining is then done with erosion technique and extremely precise grinding because the weight of each blade has to be exact so there is no vibration and imbalance.

[@mememaster147]

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.

[@anthonylepore516]

That was incredible! You should do an episode about single crystal superalloy turbine blades. They're even more durable and the manufacturing process is super interesting. Might not be something you can demonstrate at home though.

[@ph11p3540]

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

[@dergunter1237]

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.

[@lorez201]

@@ph11p3540 I hate trade secrets so much lol.

[@AndrewMerts]

@@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, kzbin.info/www/bejne/Z6urhH5jg9GUsJI and an excellent video by AgentJayZ kzbin.info/www/bejne/oHTFZ2CCfMuYfsk

Important correction: Young's Modulus (AKA Modulus of Elasticity) does not change much with temperature, the Yield Stress does. Hot steel is nearly as stiff as cold steel, but the amount it can deform elastically is much less. Also, I don't think aluminum powder is capable of reducing titanium dioxide, I think you need magnesium powder for that.

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.

Inco is fun. it welds like a stainless aluminum blend. I worked at an electron beam welding shop for a few months and that would punch a 2"+ deep weld with a 0.02" heat affected zone. We were doing things like welding parts of the rotating assembly of 737 max engines and things like that. it was really fast too, like 100+ inches/min. at production speeds. if you tried to slow down, the weld would "fall out" because it was overheated. the beam would just slice right though and into the other side of the part. the whole process was done under high vacuum in a giant chamber, and the beam is steered with electromagnets. the welds would offgas inco and vapor deposit it in the chamber, so we had to swap out glass slides to see, and the lights inside the chamber were mirrors on the inside and just dull gray on the outside instead of you know... releasing light.

[@embersaffron5522]

[@seldoon_nemar]

@@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

Inconel is also used as material used to grind other materials because of its toughness. There is however an issue, it looks like cast iron after it's been used for a while. The problem isn't cosmetic, the problem is if it gets recycled, the material won't melt into iron. The results are billets of iron that are unmachinable because the cutting tools keep being broken off. It's a real problem

How about a follow up video covering crystal control when casting super alloys, how a cold block on one end of the casting mold and a hot kiln on the other end creates linear crystal growth, like a bundle of rods. The addition of a pigtail after the cooling block forces the multiple rods into mono crystalline structure. All of that happens before the solidification of the cast blade itself, which will be mono crystalline. Mono crystalline castings exhibit the greatest strength and stiffness of super alloy turbine blades. The inability to create mono crystalline super alloy blades prevents the chinese j20 from achieving super cruise. If they want to fly as fast as Americans they need to use after burner, which gobbles up fuel and provide a great signature for heat seeking missiles. Making their stealth plane, non stealthy.

I was gonna criticize you for using a thermite reaction instead of the induction heater but then melting the nuggets in the heater, but I don’t blame you for wanting to make thermite. I’d do it too

when i was a machinist i machined inconel crap is it difficult.. i forget off hand the inserts we used but from what i remember they were expensive and didn't last long..

And this is why Elon Musk chose this category of super alloy for his under development Starships. Very hard to impossible weld with traditional methods except for friction stir welding by robot and tricky to machine. Starship uses different kinds of Inconel but the one discussed in this video is used in the rocket engines
