  2. 1. Microstructure of a cubic boron nitride tool material and its degradation during hard turning operations

    Author : Jenny Angseryd; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDX; adherent layer; cBN; PCBN; SEM; TEM; EELS and APT; wear; EFTEM;

    Abstract : Abstract. Polycrystalline cubic boron nitride (PCBN) materials are widely used in turning operations of hardened steels due to their beneficial mechanical properties like maintained high hardness at elevated temperatures, adequate toughness and for being more chemically stable towards iron compared to diamond at temperatures typical for turning operations.
