Project Description

This project will combine materials informatics and physics based modeling for an ICME approach to predict long-term creep behavior in Ni-based superalloys for advanced ultra-supercritical steam turbine applications. This project will apply advanced materials informatics for critical assessment of existing experimental data from creep tests on selected alloy, evaluate existing models to ascertain confidence on creep-life predictions and determine which if any provide a statistically adequate fit to the data and safe extrapolation of the data, and develop new modeling capabilities needed to predict long-term creep behavior of Ni-base superalloys for use in A-USC coal-fired power plant steam turbines.

Project Benefits

Improved efficiency and accuracy in assessing the Ni-base superalloy’s long-term creep performance, accelerated development and qualification of new materials for next generation A-USC steam turbine systems, and increased efficiency of coal-fired power plants and reduced emissions.
