Residual stress distribution in Ni-based superalloy

Ni-based superalloy gas-turbine-engine discs have been developed and employed in aerospace and land-based power-generation applications. Historically, attentions have been mainly paid to multiscale microstructure evolution during the manufacturing process of typical Ni-based superalloys, including Inconel-718 , Waspaloy and Rene 88 DT . However, in practice, the service life of turbine disc is

Fatigue life prediction and failure analysis of a gas

A numerical prediction of the life of a gas turbine model disc by means of the finite‐element technique is presented and the solution is compared with an experimental rim‐spinning test. The finite‐element method was used to obtain the K solution for a disc with two types of cracks, both at the notch root of the blade insert and located in the corner and in the centre.

Finite Element Analysis to Verify the Structural Integrity

Gas turbines are very important because they can be used in several areas, such as aeronautics and electric power generation systems. The operation of a gas turbine can be done by less pollutant fuels when compared to traditional kerosene, for example, resulting in less degradation to environment. Gas turbines may fail from a variety of sources, with the possibility of serious damage results.
