This comes from a slightly related question about blisks. A blisk is a single component shaped like a disc with blades on it. This can be for compressors or turbines.
I want to ask about the turbine possibility here. Are turbine blisks common on relatively new jet engines, either commericial or military? It's arbitrary, but take "relatively new" to mean designs that went into production within the last 10 years, maybe give or take a few years.
The turbine has the most difficult alloy, superalloys, so I am wondering if blisk manufacture is made more difficult because of this or is infeasible for some reason. (Note the blisk has several disadvantages, like if one blade is damaged the entire blisk needs to be taken out and repaired/replaced, but that alone doesn't suggest to me why turbines would be more problematic than compressors.)
Just for reference, the first turbine stage needs to handle temperatures of 1700 to 1800 K.
