| 内容： | The present invention relates to a ceramic material based on based on -sialon (Si 6-z Al z O z N), +--sialon, a refractory hard phase comprising TiN, Ti(C,N) or TiC, an intergranular amorphous or partly crystalline phase, and containing yttrium. The -sialon phase has a z-value of 0.3-0.8. The content of refractory hard phase is 10-20 percent by weight. The material is particularly useful as cutting tool inserts for the machining of heat resistant super alloys (HRSA). |
