This Phase II STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPam1/2) ultra-high temperature HfC-based composites (UHTC) with an outstanding oxidation resistance for advanced rocket nozzle throat components. UES will apply a novel"Top Down"approach to control the microstructures of the composites. This approach will produce a very unique grain structure that can offer high strength, high fracture toughness, and high oxidation resistance. Field Assisted Sintering or Hot-pressing will be used as a means for densification during the Phase II study. During the Phase II program, UES will collaborate with the University of Alabama and Southern Research Institute to conduct microstructural characterization and to evaluate high temperature properties. Approved for Public Release 14-MDA-8017 (16 October 14).
