Divided into many superalloys, and nickel-base single crystal superalloy is one of the most typical representative of this is because it has a lot of excellent performance, has become the manufacture of advanced aircraft engines and gas turbine blade main material. This high temperature alloy which has gone through several stages in the development process it?

In order to meet the high performance aeroengine design needs, we have been carried out research and development for the nickel-base single crystal superalloy. With the improvement of the production process and improve the theoretical level of alloy design, have appeared higher temperature capability of the second generation single crystal alloy and third generation single crystal alloy, using temperature can reach 1204 ℃, while also having obvious creep strength advantage.
At present, the fourth generation single crystal alloy RR3010 has appeared, its temperature bearing capacity of up to 11800 ℃, because the alloy by adding a variety of new elements, so long-lasting performance and resistance to environmental performance of the new single crystal alloys have significant improved.
