Abstract
Composite materials are provided based on titanium diboride and processes for their preparation. The composite materials contain (1) 70 to 98% by volume of titanium diboride, (2) 1 to 15% by volume of Fe.sub.2 B and (3) 1 to 15% by volume of Ti.sub.2 O.sub.3 and have the following properties: density at least 93% of the theoretically possible density of the total composite material, hardness (HV10) greater than 1,900, bending fracture strength (measured by the three-point method at room temperature) at least 400 MPa and fracture resistance K.sub.IC (measured with a sharp incipient crack produced by the bridge method) of at least 4.5 MPa.sqroot.m.
