    Fabrication and characterization of B4C nanowires and dense B4C ceramic/nanowires composite by Chua, Miao Jun.

    Published 2012
    “…It had a KIc value of 3.90 ± 0.10 MPa•m1/2, which showed a 78.0% improvement as compared to the pure B4C ceramics (2.1-2.2 MPa•m1/2). Due to reduction in the content of hard B4C phase, compared to monolithic B4C samples, the hardness of both the B4C-TiB2 and B4C-BCNWs composites was decreased with increasing contents of TiB2 and BCNWs. …”
