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.
