Project Description

The goal of this project is to develop practical engineering solutions on two (2) key issues on the weldability of high-temperature creep-resistant alloys used in advanced fossil energy power plants - the reduced creep strength of the weld region vs. the base metal, and welding of dissimilar metals. The project will use an integration of materials welding science, advanced experimental and characterization techniques and computational materials modeling to develop usable solutions to these issues.

Project Benefits

Will lead to advanced power plant designs that can operate at higher temperatures and pressures, which will lead to improvements in efficiency, operational flexibility, and lower capital and operating costs.
