The AR and TD Materials Program is directed toward obtaining a fundamental understanding of materials and their behavior in fossil energy systems. Long-range needs of fossil energy systems are addressed on the program and funded projects should have general applicability to several fossil energy technologies. Three research thrust areas are included in the program: structural ceramic composites, alloy development and mechanical properties, and corrosion and erosion of alloys. A programmatic activity on assessments and technology transfer is included. Principal activities on the structural ceramic composites research thrust area include the development of processes for making silicon carbide whiskers, and incorporating whiskers into ceramic matrix composites. Two major alloy development projects are being conducted. The first of these is the development of iron aluminides. The primary development effort on the aluminides has led to the identification of alloy compositions with combined high-temperature strength and corrosion resistance. The second alloy development project is the development and evaluation of iron-base alloys for advanced coal combustion heat exchange systems. Corrosion research centers on studies of the formation and breakdown of protective oxide scales, particularly in sulfur-containing atmospheres. Erosion and wear research is directed to the understanding of modes of material erosion and their relationships to materials properties. 28 refs., 4 figs., 1 tab.
