High Temperature Microstructural Degradation of Haynes Alloy 230

Haynes Alloy 230 TM is a solid solution strengthened nickelbased material used for combustion components in industrial gas turbines. In this application a primary limit to the component design life is the response of the material to high temperature exposure with and without mechanical loading. Over long periods of operation in service, this leads to degradation of the microstructure of the alloy and consequently to its mechanical properties. A detailed understanding of the processes associated with in-service the microstructural degradation of the alloy and its effects on the mechanical properties of the material is therefore of great importance in the drive for increased component life and reliable extended plant
