Abstract

Under this STTR, Deep Springs Technology (DST) in cooperation with Georgia Tech is testing the feasibility of producing high strength Mo-Si-B composites based on the Georgia Tech method of ultrasonic spray drying Mo, Si3N4, BN powders, reacting the granules at high temperatures to MoSiB composites, and reduction extruding the sintered granules at high temperature into dense composite rods. The GT Reaction Sintered (GTRS) process, in Mo3Si1B composition, has been demonstrated to provide low interstitial impurities (O, C, N) and to produce both microstructures, oxidation resistance up to 1200C, and high temperature, high strength, ductility competitive with MoSiB composites from other processes. However, high temperature extrusion or similar deformation may be required for MoSiB composites to have oxidation resistance to 1300C and to produce defect free, structural material on an industrial scale with the necessary reliability required for high safety margin applications such as aircraft engines.
