hmmm.. well i can't tell you what alloy it is, except it's a new generation (5th??) nickel based gamma/gamma prime directionally grown single crystal superalloy.
and then i electroplate platinum on top and heat treat to diffusion bond the platinum to the substrate..
i thought i'd killed the superalloy structure, but the temp should have been too low for that.. turns out there was more inter-diffusion than we thought and the original structure is found much deeper in the alloy...
the platinum is relatively immobile, so it's probably just nickle and tantalum shifting the gamma/gamma prime loop and de-stabilising the two phase cube structure.....
or something like that
