Abstract:
Ni-based superalloys are widely used in aerospace and power generation as gas turbine components due to their excellent high temperature performance. These components are subjected to a combination of elevated temperature, high stress and aggressive environments during service, which can cause significant degradation of the materials. This microstructural and chemical degradation deteriorates the mechanical properties such as tensile strength and creep resistance, which can lead to failure in the components and reduce their service life. When a superalloy power plant gas turbine component reaches the end of its predicted life, the user typically has two options: replace the component or attempt to extend its remaining life.
