“…They are commonly used in power plants to generate electricity, where they burn natural gas, diesel, or other fuels to produce high-pressure gas that is used to drive the turbine and generate power (Sivakumar andMordike 1989, Salwan, Subbarao et al 2021). Additionally, gas turbines, also known as jet engines, are used to propel airplanes by taking in air, compressing it, mixing it with fuel, igniting the mixture, and then expelling the combustion products to create thrust (Chowdhury, Mohsin et al 2023, Courtis, Skamniotis et al 2023. Their high power-to-weight ratio enables quick acceleration and maneuverability, making them a popular choice for naval ships and high-speed vessels (Liu, Han et al 2023, Nourin andAmano 2023).…”

The present study aims to determine the best and most economical material for a gas turbine blade, which operates under high-temperature conditions and experiences high static structural and thermal loads. To achieve this objective, three different types of material alloys, namely Titanium alloy Ti6AL4V, Magnesium alloy AZ80, and Aluminum alloy 7075-T6, were selected for comparison. A turbine blade model was designed using Solid Works software, and structural and thermal analyses were performed using ANYAS 15.0 under steady-state conditions. The structural analysis aimed to determine the stress, strain, and deformation results on turbine blades by applying high pressure, while the thermal analysis aimed to determine the temperature distribution influences and heat flux generation by applying high temperatures. Based on the results obtained from both analyses of the three different materials, Titanium alloy Ti6AL4V is the best and most economical material. This material showed low stress, strain, and little deformation and the best material properties at high temperatures when compared to Magnesium alloy AZ80 and Aluminum alloy 7075-T6.
