Integrated Design and Rapid Development of Refractory Metal Based Alloys for Fossil Energy Applications

One common barrier in the development of new technologies for future energy generating systems is insufficiency of existing materials at high temperatures (>1150C) and aggressive atmospheres (e.g., steam, oxygen, CO2). To overcome this barrier, integrated design methodology will be applied to the development of refractory metal based alloys. The integrated design utilizes the multi-scale computational methods to design materials for requirements of processing and performance. This report summarizes the integrated design approach to the alloy development and project accomplishments in FY 2008.
