The criti-cal conditions for suppressing the precipitation of brittle phase can be decribed by the elec-tronic parameters Mdt≤0.99 and Mdγ≤v0.93, which can be applied to the d-electrons alloydesign of hot corrosion resistant Ni-base superalloys with high Cr contents. They are themost important reference parameters for the alloy design practice. It was also proved that thetwo critical parameters Mdt and Mdγ are equivalent so that the Mdγ could be replaced byMdt, which will greatly simplify the alloy design process.
