Abstract-Nowadays, the practice of increasing the inlet temperature of the thermal devices like the gas turbines is existed for improving their net shaft work and their thermal efficiency. The higher the operating temperature affects the structural stability of the components. The structural stability is usually influenced by its profile and other physical shape design, type of cooling design employed, operating temperature, physical chemical nag mechanical properties at elevated temperature and loading conditions. In this research the design and cooling type are predefined. The objective of the research to investigate the appropriateness of the suitability suggested material. The investigations on the materials under the dynamic loading conditions at elevated temperature were made to find the suitability. The Pro -E used to model the blade and the ANSYS R14 work bench employed for conducting the analysis. The investigations were made separately for both materials. The results are discussed towards the appropriateness towards the guide vane designed and a minor correction in design was also suggested.
