Microstructure of base metal, heat affected zone, and weld metal.

Project Description

The goal of this project is to improve the capability to perform accurate and rapid computational modeling of the long-term mechanical behavior of nickel superalloy weldments that will be used in advanced fossil energy power cycles. An improved capability to predict the long-term behavior of weldments will allow materials scientists and structural component designers to optimize the use of advanced materials in advanced fossil energy applications. In this project, Idaho National Laboratory (INL) will develop a microstructure-based creep model for nickel superalloys and add it to a computational platform, Multiphysics Object-Oriented Simulation Environment (MOOSE), that INL has developed for multi-scale simulation of the behavior of high-temperature materials in nuclear power plant applications.

Project Benefits

The development of improved computational methods to predict the long-term behavior of advanced materials and structural components in fossil energy power plants will reduce the time and expense of developing and qualifying new materials and enable a more cost-effective use of advanced materials at higher operating temperatures and pressures, which will result in higher efficiency fossil fuel-based power systems.
