In modern power generation systems, turbine blades are made up of nickel based super alloys, generally Inconel or Nimonic alloys. Three widely used Inconel alloys namely Inconel 718, Inconel 625 and Inconel 738 are being selected for virtually constructing the blade and analysis purpose after going through several research works in the relevant field. The present work is concerned with determining the best suited Inconel alloy among the three commonly used alloys mentioned above under a set of working parameters. An individual turbine blade has been modelled using SOLIDWORKS 2016. All the three materials are being virtually generated and the analysis work is carried out in the Finite Element Analysis software ANSYS Workbench V14.0. The results obtained from the analysis have been used to determine the total deformation, principle stress, principle strain and strain energy for each material under variable pressure and constant turbine inlet temperature. It is observed from the analysis that Inconel 625 has been found to exhibit better suitability and characteristics.
