posted on 2014-08-05, 10:33 authored by Zhiqi YaoNi-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. [Continues.]
