Fractographical characterization of hot pressed and pressureless sintered SiAlON-doped ZrB2–SiC composites

ZrB2–SiC composites doped with 0, 1, 3 and 5wt.% SiAlON were prepared by hot pressing (under a low pressure of 10MPa) and pressureless sintering processes at 1900°C for 2h. A fractographical approach was employed to investigate the effects of SiAlON addition on the densification behavior in such cer...
