Abstract
A CBN compact comprises CBN and a matrix phase incorporating a secondary hard phase selected from TiCN, TiC, TiN and mixtures and solid solutions thereof and a maximum amount of titanium diboride where the XRD peak height of the (101) titanium diboride peak (after background correction) is less than 12% of the peak height of the (111) CBN peak.
Claims18
A CBN compact comprising CBN particles and a matrix phase incorporating a secondary hard phase selected from TiCN, TiC, TiN, mixtures and solids solutions thereof and a maximum amount of titanium diboride defined as the XRD peak height of the titanium diboride (101) peak, after background correction, being less than 5% of the peak height of the (111) CBN peak, where the CBN compact contains 35 to 75 volume % of CBN.
