Joining of Advanced High-Temperature Materials

The objective of this project is to develop the joining technology required for high-efficiency, low-emissions fossil energy conversion in support of U.S. Department of Energy Office of Fossil Energy clean coal programs. Focus will be on oxide dispersion strengthened alloys and nickel based superalloys.

Project Benefits

This project will demonstrate joining of advanced high-temperature materials. Development of effective joining methods to maintain the material performance of high-performance alloys will enable their use in high-temperature, high-pressure, corrosive environments, including advanced ultrasupercritical steam turbines and boilers. Improvement to high-temperature advanced materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, with improved efficiency and operational flexibility, resulting in lower capital and operating costs.
