Toughening of ZrB2-based composites with in-situ synthesized ZrC from ZrO2 and graphite precursors

ZrB2 matrix composites toughened with in-situ formed ZrC were fabricated by spark plasma sintering (SPS) utilizing ZrB2/ZrO2/graphite powder mixtures at 1900 °C for 7 min under 40 MPa load. Different amounts of graphite nano-flakes (3, 6, and 9 wt%) were added to ZrB2–20 vol% ZrO2 aiming in-situ for...
