摘要：
Effects of yttrium on the mechanical property and the cutting performance of Al2O3/Ti(C,N) composite ceramic tool material have been studied in detail. Results show that the addition of yttrium of certain amount can noticeably improve the mechanical properties of Ai(2)O(3)/Ti(C,N) ceramic material. As a result, the flexural strength and the fracture toughness amount to 1010MPa and 6.1MPam(1/2), respectively. Results of cutting experiments indicate that the developed ceramic tool material not only has better wear resistance but also has higher fracture resistance when machining hardened 45 steel. The fracture resistance of the Al2O3/Ti(C,N) ceramic tool material with the addition of yttrium is about 20% higher than that of the corresponding ceramic tool material without yttrium.
