Addition of WC and Co liquid phase resulted in considerable increase in flexural strength up to 1085 MPa for the 1 wt% AlN, 0.5 wt% B, and 20 wt% polycarbosilane-added specimen. The improved flexural strength was a result of surface compressive layer. The surface compressive layer was introduced by the liquid flow phenomenon during hot pressing.
