ABSTRACT:
A sintered ceramic material for high speed machining of heat resistant alloys is provided comprising SiAION grains and 0.2-20 v/o intergranular phase. At least 80 v/o of said SiAION phase is beta SiAION having a z-value greater than 1.0, but less than 1.5. The ceramic material has a Vickers Hardness HV1 of more than 1530 and it is produced by gas pressure sintering.
