The metallic materials discussed briefly in this report are nickel aluminides, nickel-iron aluminides, Fe{sub 3}-Al-based iron aluminides, and advanced austenitic alloys for coal utilization applications. Whisker-reinforced ceramic composites, toughened zirconia ceramics, fiber reinforced composite hot-gas filters, and titanium diboride are all discussed. The sol-gel process for the fabrication of high-yield oxide varistors is presented briefly. The use of zirconia-bonded zirconia for fiber insulation structures is presented. The patent status for all the metallic and ceramic materials and for their uses is reported. Several methods for testing the materials described include pulsed eddy-current non-destructive, Sigmajig (an improved hot-cracking test), and laser diffraction measurements for high-temperature strain measurements. MHD molten metal atomizer for powder production, thermal spraying, and microwave sintering of ceramics are all described. A process for impregnating a concrete or ceramic body with a polymeric material and a thermomechanical software development center are both discussed briefly. (BM)
