> and especially not the trade secrets of how the entire blades are grown from single crystals

Wait, what? Are you telling me that jet turbine blades are one single crystal instead of having the usual crystal structure in the metal?

I'm not a materials guy personally so won't be the best person to explain the exact science behind them, but they're definitely a really impressive bit of engineering. I had a quick browse of this article and it seems to give a pretty good rundown of their history and why their properties are so useful for jet engines https://www.americanscientist.org/article/each-blade-a-singl...

Wow... Mindblowing stuff. Long but woth reading.

They are grown as single metal crystals in order to avoid the weaknesses of joints. They are very strong!

Well, clearly you're not a pilot. :P
