Welcome to the forums.
Lots of steel needs here.
Tell us about these turbine super alloys.
Where do you find meteorites? What is their composition?
This is just a quick sketch, the longer answer is best over an adult beverage with some time to hangout and chat in my workshop.
The super alloys are for high temperature strength so that turbine blades can survive in 1500+ degrees with internal cooling passages mostly alloys with high nickel content. The best ones are proprietary and are cast with a technique that eliminates all grain boundaries (the usual failure initiation point for metals at the microscopic level) so they are have only a single crystal in the entire part. Other parts that need higher strength with more cooling like the disk hubs are forgings that have the grain boundaries aligned in the needed stress direction like a folded metal sword or sushi knife, except in engines you need much more complex 3d shapes compared to a flat blade that can be simply hammered.
Just like knives, the best alloys available today are are now powdered metal configurations that can be blended and fused in ratios that wont melt together and play nice if melted the normal way.
That is what got me interested in meteorites, the ones i make watches out of are iron-nickel alloys that came from the hearts of asteroids before the earth was formed. They make a beautiful metallic crystal structure that grows over millions of years in a very slow cooling rate say 1 degree per million years lol and in zero gravity the octohedral crystals grow to sizes that cannot be duplicated in earth gravity so it is something that cannot be faked in China lol.
I was the first to play with blueing these meteorites for watch dials back in 2009 even though others like Rolex used the material before but coated it with rhodium to prevent rusting. Take a look at TimeEngines.com if you want to learn more. Some other meteorites are stony like the moon (which I was the first to make a watch dial from) and mars (which is generally a greenish colored rock due to olivine content).
How do I find them? I don't but In Arizona we have the largest majority of meteorite hunter professionals for some reason. I studied engineering at ASU which has probably the worlds largest meteorite lab. Some of my friends are in the top of this field and the first to discover new meteorites and have them classified at ASU in return for letting the university keep a portion for their vast collection. I buy meteorites from them. There is something special about wearing something on your wrist that older than the earth itself 4.5+ billion years. I suppose I should attach a couple of pics, I should mention it is just a hobby I don't make money off the watches they are just a hobby and collected mostly by friends and family. They take too much time to make to be profitable using my old fashioned manual machining techniques lol. Here are a couple pics of meteorites and watches...
