Nickel based single crystalline superalloys are irreplaceable materials for blades of aero-engines due to their superior mechanical properties and corrosion resistance at high temperature. A small amount of rhenium (Re) can significantly improve both temperature capability and mechanical properties of nickel superalloys which is referred to as “Re effect”. This paper briefly reviews research progresses on the distribution of Re in nickel superalloys, and the corresponding strengthening mechanisms. A discussion on the future researches and challenges on the study of “rhenium effect” are prospected.
