Wait, what? Are you telling me that jet turbine blades are one single crystal instead of having the usual crystal structure in the metal?
- motives 5y agoI'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-single-crystal https://www.americanscientist.org/article/each-blade-a-singl...
