Gas Turbine, Turbine blade, Ni base superalloy, Low cycle fatigue.Abstract
Design of Turbo machinery is complex and efficiency is directly related to material performance, material selection is of prime importance. Temperature limitations are the most crucial limiting factors to gas turbine efficiencies. This paper presents the life of GTD 111 applied to gas turbine blade based on High temperature tensile test and LCF test results. The LCF tests were conducted under various strain ranges based on gas turbine operating conditions. The paper will focus light on above issues and each plays an important role within the Gas Turbine Material literature and ultimately influences on planning and development practices. It is expected that this comprehensive contribution will be very beneficial to everyone involved or interested in Gas Turbines.
