Simple question, but somehow the answer has eluded my searches.

The material is used in turbine blades.
I've seen it also called CMSX-4

I just want to find out what the conductivity and permeability of the
single crystal structure is.

And, then what the conductivity and the permeability of the material
when recrystalization occurs.

Anybody have a table, or reference?

Thank you for the exact URL. I think I found this on a google search, but the Cambridge Press so obfuscates what is there was not certain it was what I wanted. Couldn't view anything other than the title, authors, NO abstract.. just a sentence. But, wanting $45 for a copy was predominate! Yeah, I always buy something before I know what it is.

Just need some numbers. Simple, I don't want a great long dissertation on how they used some electron microscope etc. just need a @#$%#@ table, like .gov and NIST publish all the time.

Maybe email the material scientists are Georgia Tech with your question? They are easy to find there.

Is this about chrome-nickel superalloys? Those are suited
for LARGE temperature swings, I'd imagine conductivity will be
hard to model. Ferromagnetism isn't a problem, at least
with most of the ones I've seen (Inconel and Hastelloy).

Good suggestion. I tried that found Prof. Rosario Gerhardt's name, email right away, but Cui, didn't appear to be ientical Culmination, emailed a similar reuest to them.

Why? no relative permeability? well, stays at 1?

Yes, that was what I meant. Pure nickel IS ferromagnetic, but not the
US nickel coin (Ni-Cu alloy) nor most of the superalloys (Inconel X-750
for instance, 70% Ni, 15-18% Cr).

Thank you. Interesting how putting ferro into an alloy destroys the magnetic properties, eh?

Any idea how much the conductivity changes with Rx?
1%? 10%? none? Something HAS to change since the surface chemical properties change.
