Abstract: Although it is commonly known that the commercially available Si3N4-based inserts are not suitable for the machining of steel, because of the detrimental chemical incompatibility of Si3N4 with iron-based alloys, this work shows that composites with a thermodynamically, more favourable SiAlON matrix, toughened and hardened by a secondary phase can be used. Successful high speed dry turning of DIN 42CrMo4 steel with SiAlON-TiX composites is demonstrated. The results of two types of sialon matrices with 30 volume percent of TiB2, TiCN or TiN are reported and are compared with that of three commercially available Al2O3-based cutting tool materials.
