titleOfInvention Ceramic material and cutting tools made thereof for applications demanding good notch wear resistance
abstract The present invention relates to a ceramic material consisting of β-sialon (Si 6 - z Al z O z N), polytype 12H, an intergranular amorphous or partly crystalline phase, and containing yttrium with a z-value of 0.7 - <1.5. The ceramic material is useful as cutting tool insert for machining of heat resistant super alloys, with good notch wear, acceptable flank wear and sufficient toughness.
