Abstract

High-density SiC-TiB₂ composites were fabricated using the displacement reaction spark plasma sintering/field-assisted sintering technology (SPS/FAST) and SiC, B₄C, TiC, and Si powders. The reaction process was performed in a narrow time frame compared hot pressing. The SiC-TiB₂ composites were sintered with precursor SiC at various pressures to determine the effects of processing with SPS/FAST. The composites completed synthesis during SPS/FAST processing, which occurs more quickly than hot pressing. SEM, STEM, and Raman spectroscopy are used to show the conversion and microstructure. The composite of 53.6 wt.% SiC and 46.4 wt.% TiB₂ has 99 % theoretical density, hardness of 26.4 GPa, and fracture toughness of 5.12 MPa m^1/2.
