Nickelbased superalloys used for the combined cycle system should be superior in both the hot corrosion resistance and the oxidation resistance compared to the superalloys used for jet engines. This is because the total service duration is much longer in this system than in the jet engine of the aircraft, and also the

Superalloys Trivia The term “superalloy” was first used shortly after World War II to describe a group of alloys developed for use in turbosuperchargers and aircraft turbine engines that required high performance at elevated temperatures.

Abstract. From the first forged turbine blades made of iron base alloys to the present nickel base singlegrain turbine blades and vanes manufactured by directional solidification, an enormous amount of research has been directed to attaining the hottest possible combustion chamber temperatures in jet engines.

Metal Injection Molding for Superalloy Jet Engine Components 9 4 RTOMPAVT139 UNCLASSIFIED/UNLIMITED UNCLASSIFIED/UNLIMITED powder of these superalloys can be used either for forging, investment casting or for generating powder.

Superalloys, on the other hand, possess many properties required by a jetengine material such as high strength, long fatigue life, fracture toughness, creep resistance …

The modern jet engine has completely transformed the way we travel, conduct business and connect with the world. This intricate feet of engineering has helped thrust our worlds together and is set to have a potentially huge impact on the future of air travel.

The combustor and turbine components in aircraft engines operate at redhot temperatures while rotating at high speeds. They are made of nickel, cobalt or iron superalloys to withstand the extreme temperatures and cyclic stresses. Forty percent of the engine weight typically consists of superalloys.

Business expansion is another strategy adopted by the aerospace superalloys market players to gain competitive edge. For instance, in May 2014, Alcoa invested USD 100 million to expand its facility in Indiana for the production of nickelbased superalloy jet engine components.

COLUMBUS, Ohio—Researchers here have made a discovery in materials science that sounds like something from the old Saturday morning cartoon Super Friends: They’ve found a way to deactivate “nano twins” to improve the hightemperature properties of superalloys that are used in jet engines.

Superalloys are rightly named due to their extraordinary mechanical properties and oxidation resistance at elevated temperatures. These alloys find application at most demanding service conditions like the hottest section of jet turbine engines, space shuttle engines etc.

While superalloys gained their popularity through uses in jet engines and space shuttle engines, they continue to find other uses where high temperature performance is demanded – like in nextgen high performance turbochargers for automotive engines.
