摘要

Fully dense β-SiC ceramic has been sintered at low temperature (1500°C) by spark plasma sintering (SPS) with Y₄Al₂O₉ (YAM) and Y₂O₃ as additive. The sintered SiC samples have an interlocking and laminated microstructure of elongated grains, and reveal excellent mechanical properties. High hardness (31.2±1.54GPa) and fracture toughness (6.6±0.37MPam^1/2) are obtained simultaneously in SiC ceramics, which are quite different from previous researches. The indentation image shows that there are several different toughening mechanisms co-existing, which interact and further improve the fracture toughness of SiC ceramics.
