PURPOSE: To attain the sintering of TiN at a low temp. by adding Al and to ensure high performance of the resultant sintered compact because the added Al is converted into TiAl3 and AlN excellent in heat resistance and mechanical characteristics by a reaction with the TiN. CONSTITUTION: Aluminum is added to TiN powder by 3-20wt.% and they are hot-pressed in vacuum or in a nonoxidizing atmosphere of Ar, N2 , etc., under the conditions of >=1,300 deg.C temp. and >=150kg/cm<2> pressure to obtain the objective sintered compact having high strength, high hardness, a high m.p. and high electric conductivity. |
