ABSTRACT:
An improved modified silicon aluminum oxynitride based composite cutting tool is made by forming a homogeneous matrix of a modified silicon aluminum oxynitride prior to uniformly dispersing a hard refractory material throughout the homogeneous matrix, then densifying the combined materials to form a composite cutting tool having a density greater than 98 percent of the theoretical density of the combined materials.
