Gas turbines are currently one of the most efficient turbo machinery sources. This technology has applications in numerous sectors, including manufacturing, aerospace, household, and small-scale enterprises. Gas turbine engines present many challenges when choosing blade profiles, selecting materials, and controlling turbine rotor blade vibration. The influence of these factors on structural performance and stress deformation is significant. The total heat flux, the directional distortions of the turbine blades, and the thermal error resulting from the interaction between the heat and centrifugal loads have all been analyzed. In addition, the temperature flow is a result of thermal loading. The results for three materials (Inconel 718, titanium T6, and SS316) are compared to choose the optimum material for a turbine blade
