Physico-Chemical and Technological Peculiarities of Producing the Thermally Stable Alloys Containing Rhenium

Abstract

The analysis of works on the creation of modern nickel-base superalloys for casting the gas turbine single crystal blades was performed. The alloying features, the phase composition and physicochemical factors of high-temperature strength of nickel-base superalloys with rhenium content are considered. The principles of balanced alloying and the computerized designing methods of single crystal nickel-base superalloys with increased content of Re (9-10%) are also considered. The role of the high-gradient directional solidification in the manufacture of single crystal turbine blades from high-rhenium nickel-base superalloys is discussed.
