Nasa has invented Duranium!

NASA's New Material Built to Withstand Extreme Conditions
NASA innovators recently developed a new metal alloy using a 3D printing process that dramatically improves the strength and durability of the components and parts used in aviation and space exploration, resulting in better and longer-lasting performance.
NASA Alloy GRX-810, an oxide dispersion strengthened (ODS) alloy, can endure temperatures over 2,000 degrees Fahrenheit, is more malleable, and can survive more than 1,000 times longer than existing state-of-the-art alloys. These new alloys can be used to build aerospace parts for high temperature applications, like those inside aircraft and rocket engines, because ODS alloys can withstand harsher conditions before reaching their breaking point.
[...] . NASA's new alloys deliver enhanced mechanical properties at extreme temperatures. At 2,000° F, GRX-810 shows remarkable performance improvements over current state-of-the-art alloys including:
- Twice the strength to resist fracturing
- Three and a half times the flexibility to stretch/bend prior to fracturing
- More than 1,000 times the durability under stress at high temperatures
"This breakthrough is revolutionary for materials development. New types of stronger and more lightweight materials play a key role as NASA aims to change the future of flight," said Hopkins. "Previously, an increase in tensile strength usually lowered a material's ability to stretch and bend before breaking, which is why our new alloy is remarkable."
I guess Elon has to build a Raptor 3 with it.

Durand-Durandium, though, is very enjoyable, if Jane Fonda is any indication.

Naive me- years ago I first saw it on TV, cut and trimmed of course. But I didn't know it had been cut, so I certainly didn't know what had been cut out. So I tried to follow the plot and make sense of it. More than once. Sigh.

Turbine discs need to be extremely rigid so they don't hit the stators under load and they can't stretch or they'd hit the case. The combustion chamber and maybe the bell would be candidates for this material since the tolerances aren't as tight. If the material is cheap enough and can also withstand extreme cold then Starship's hull is another candidate. On the other hand 3d printing is straight up Rocket Lab's and Relativity's alley so I expect that they are at least looking at this for their own rockets.

Do we have any idea if this is any stretchier than what they're using now? I believe the stated flexibility mean it can be stretched 3.5x further before breaking, it says nothing about what forces are needed to do that. It might behave the same as the reference material under the same conditions, but can be pushed to much more extreme conditions before breaking.
Because the thing is that *everything* flexes under load - even diamond (not much, but some). And that gets taken into account when designing high-speed precision turbines, etc.: At rest the turbine is actually slightly too small for the case, then it stretches to the perfect size when spinning at normal operating speeds.

NASA has a patent portfolio that they licence to businesses. This likely falls in that category since this type of research is how they get those patents in the first place.

I think it's safe to assume some private entity will own the rights / profit to said discovery.
That's America.
Privatize the profits. Socialize the losses.
It's just good business.

As I said to a previous poster, NASA patents its research and then licences it to private companies.

1093.333 degrees celsius. TFA does not say, and with science being made in C/K, it could be 1100 rounded in "translation" to 2000 freedumbs. Or maybe NASA nailed it and it's 1093.333333333333333333333... C.

Of course the scientific way would be to use Kelvin. Which makes 1366.48 K. Or rather over 1366.48, which might be 1400K.

Alloys, by definition, are alloys of something. What is the base metal being deployed? Or does 3-D printing and oxide dispersion negate the need for any actual information? Aluminium? Titanium? Unobtainium?

Element 457 of course!
Our periodic table isn't remotely complete, and I know of no reason to assume that some of the higher elements couldn't have stable, naturally occurring isotopes that might form under particular conditions that just didn't happen to be present in our little corner of the galaxy before Earth formed. Or it is present, but in such low concentrations that we haven't discovered it yet. Or the particulars of our planetary formation mean that it all settled into our core before a solid crust began to form to trap it on the surface.
It could also be some bizarre alloy of materials that individually exist on Earth, but that can only alloy in exotic conditions that we couldn't recreate, and must therefore be carefully maintained in its alloyed state - e.g. melting it might completely destroy its properties.
