help! what are the electrical characteristics of single crystal nickel based superalloys?

Jun 20, 2013 9 Replies

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 t he 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 alw ays buy something before I know what it is.

Just need some numbers. Simple, I don't want a great long dissertation on h ow 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? Th ey are easy to find there.

Authors is what I meant...

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?

problem, at least

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).

problem, at least

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.
