Abstract Scope |
The efficiency of such supply is dependent on the operating parameters of the plants but at the expense of the useful life of the components. Turbine blade is one of the components that contribute immensely to such efficiency and it should be made of high-strength material with ability to withstand the harsh operation environment. The properties of spark plasma sintering (SPS) technique produced NiCrCoTiAlW-Ta superalloy was used in finite element analysis software, Abaqus CAE/2017 to simulate the thermo-mechanical behaviour of steam turbine blade. The maximum thermo-mechanical stress and strain was developed on the root of the turbine blade and the value of the maximum stress developed is far below the yield stress of the superalloy. Hence, SPSed NiCrCoTiAlW-Ta superalloy is suitable for turbine blade production as such blade will survive several thermo-mechanical stress and strain cycles prior to failure. |
