I am just stating what is almost certainly the case. Inconel is difficult to cast, very expensive to machine and is not that easy to obtain. If the engine is running correctly then the temperatures should not require the use of Inconel.
The photos of the JJ NGV's that have been distorted by excessive heat when the engine has not been running correctly would confirm it, Inconel would not deform in the same way.
