A novel method, namely flash spark plasma sintering (FSPS), combining flash sintering and electric field assisted sintering, was utilized to densify boron carbide/titanium diboride (B4C/TiB2) composites. Further, sintering homogeneity of the composites with different contents of TiB2was systematically investigated and theoretical model was built. Results indicated that addition of 50 wt% TiB2 led to the densification of B4C/TiB2composite by up to 97.7% with regional range 1.9% at 1872 °C under pressure of 4 MPa in 60 s. The preferential pathway of TiB2network proves to disperse the central current and distribute thermal flow throughout the specimen possibly via tunneling, electronic field emission effect at first stage and lower-resistance composite pathway latter, contributing to the increased homogeneity.
