## Description

- description: Microstructure evolution in bulk hafnium diboride ceramics prepared
    by spark plasma sintering in flash regime was compared with conventional spark
    plasma sintering. The conventional and flash spark plasma sintering resulted in
    ceramics with a high relative density exceeding 96% of their theoretical density.
    A remarkably fine grain size distribution was noticed for the specimen prepared
    in the flash regime. This atypical microstructure evolution provides a possible
    insight into the mechanism of flash sintering for conductive bulks. The room temperature
    flexural strength of the hafnium diboride processed by flash SPS was 650 MPa which
    is 140 MPa higher than the sample produced by conventional SPS.
