PURPOSE:To provide a titanium diboride-based sintered compact having high strength, high hardness, excellent corrosion and heat resistance and very high fracture toughness. CONSTITUTION:A titanium diobride-based compact contg. 0.5-99.5 pts.wt. (expressed in terms of V and Mo) vanadium compd. and/or molybdenum compd., 1-50 pts.wt. nitride, 0.5-10 pts.wt. carbon and 1-50 pts.wt. zirconium oxide in titanium diboride is subjected to atmospheric sintering at 1,600-2,200 deg.C in vacuum or in a nonoxidizing atmosphere to produce the objective titanium diboride-based sintered compact. |
