The effect of micro-scale TiC and micro-scale TiN on mierostructure and meabanical properties of ceramic tool materials Al2O3-3Y-ZrO2were investigated systematically. The fracture toughness of ASTm20Z （ Al2O3-3Y-ZrO2-TiCm ）fabricated by adding micron-scale TiC into Al2O3-3Y-ZrO2 composite materials decreases. Ceramic tool materials A5Nm20Z fabricated by adding micron-scale TiN into Al2O3-3Y-ZrO2 composite materials have optimal mechanical properties when its fabrication technology is a fabrication temperature of 1650℃, a duration time of 30min and a sintering pressure of 30MPa, and its flexural strength, fracture toughness and Vickers hardness are 845.14MPa, 4.87MPa· mu2· 16.40GPa respectively.
