The vanes are made of a nickel base alloy and covered with a thermal protective coating.The high-pressure turbine rotor front shaft forms the structural connection between the high-pressure com-pressor and the high-pressure turbine.It is made from a nickel-chrome alloy.The front flange on the shaft is Figure 4-59.CFM56-7 high-pressure turbineHigh-Temperature Nickel-Base Alloys For Marine And ·Appendix 2 Rotor Pictures; Introduction.This RFP includes some general information required for manufacturing of a 76 MW gas turbine rotor.This rotor is illustrated in picture below.The rotor blades are not the subject of this document.Design Features.Iso Base Load Rating 76 MW Generator Set,Single Shaft
Nickel-base superalloys have excellent durability against high temper-atures,so they have been frequently used for small parts that must be used at high temperatures,such as engine parts in airplanes and gas turbines.However,in order to make a large turbine rotor that weighs more than 10 t out of a nickel-base superalloy,something that hasNickel-Based Superalloys - an overview ScienceDirect TopicsNickel-based superalloy is the most used material in turbine engines because of its high strength and long fatigue life combined with good resistance to oxidation and corrosion at high temperature.Nickel-based superalloy is the material of choice for the hottest engine components that are required toNickel-Based Superalloys for Advanced Turbine Engines May 23,2012·Evaluation of microstructural degradation and its corresponding creep property in integral cast turbine rotor made of K424 alloy.Materials Characterization,Vol.158. The development of additive manufacturing technique for nickel-base alloys A review.
May 05,2020·The high- and intermediate-temperature cast rotor ingots in steam turbines can easily be > 35,000 kg (current VIM-VAR-ESR ingot size is ~ 4500 kg,so any steam turbine rotor would need to be made of segments much like current GT rotors).Candidate alloys for rotor forgings include alloys 105,263,282,625,and 718 depending on the program.Turbocharger Turbo Turbine Wheel Investment InconelTurbocharger turbo turbine wheel investment inconel 713LC casting parts.Our Inconel 713LC casting turbine wheel applicable to turbocharger,Gas turbine and Jet engine.The material is Nickel base alloy.All of the turbine wheels are manufactured using the vacuum investment casting process.
