single turbine section is made up of a disk or hub that holds  many turbine blades That turbine section is connected to a compressor section shaft, and that compressor section can either be axial or centrifugal.The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor. The turbine blades are often the limiting component of gas turbines.Turbine blades are subjected to very strenuous environments inside a gas turbine.They face high temperatures, high stresses, and a potential environment of high vibration.All three of these factors can lead to blade failures, potential destroying the engine, therefore turbine blades are carefully designed to resist these conditions.Turbine blades are subjected to stress from centrifugal force  and fluid forces that can cause fracture, yielding, or creep failures a modern turbine faces temperatures around 1,370 °Cup from temperatures around 820 °C in early gas turbines. The high temperatures can also make the blades susceptible to corrosion failures. Finally, vibrations from the engine and the turbine itself can cause fatigue failures
