Abstract

In sintered ceramic materials based upon silicon nitride an essentially increased life of cutting inserts for chip forming machining of metals can be obtained by having the material contain (i) a refractory hard principle phase consisting of carbides, nitrides and/or carbonitrides of Ti, Nb, Ta, V, Cr, Mo, W, Hf and/or Zr, (ii) two different phases of Si-Al-O-N, alpha' and beta' phase and (iii) an intergranular phase. b
