ABSTRACT:
Composite articles, cutting tools, and wear parts are prepared by densification of a mixture comprising alumina whiskers, chopped fibers, or particles uniformly distributed in a titanium diboride matrix. Optionally, other dispersoids may also be incorporated. The preferred composite article or cutting tool has a fracture toughness equal to or greater than about 2.5 MN/m.sup.3/2. Methods of preparation and use are also presented.
