    The shape of WC crystals in cemented carbides ScienceDirect

    A shape parameter, P WC, referred to as shape equiaxiality is proposed as a quantitative parameter sensitive to the shape change of WC crystals in cemented carbides. It was shown that P WC was sufficiently sensitive to the variations in the edge length ratio ( h / b ) of the triangular prismatic WC crystals observed in the WCNi alloys of this study.
