Materials Used in Construction of Different Parts of Gas Turbine Plant

Materials Used in Construction of Different Parts of Gas Turbine Plant Points : Materials Used in Construction of Different Parts of Gas Turbine Plant Materials Material selection is of importance, and the efficiency of any machine is directly related to material performance. Turbine components must operate under a variety of stress, temperature and corrosion conditions. Compressor blades operate at relatively low temperature but are highly stressed, The combustor operates at relatively high temperature and low stress conditions. The turbine blades operate under a extreme conditions of stress temperature and corrosion. These conditions are more extreme in gas turbine. The ideal material has not been developed that will satisfy all design criteria for turbine blades. Special metal alloys meet current demand exotic materials, such as eutectic composites and ceramic are being considered for future use. However before disc using material selection. it is important to understand the general behavior of material.
