TIB2-TI(CN)-BASED COMPOSITE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To rapidly obtain a TiB2-Ti(CN)-based composite which does not require the use of fine raw material powder controlled to several μm order or below as sintering powder, allows the easy control of a non-stoichimetric property by changing the mixing ratio of the powder in spite of the raw mate rial powder having the non-stoichiometric property and has a high density, high hardness and excellent fracture toughness value. ;SOLUTION: This TiB2-Ti(CN)-base composite is prepared by sintering the powder mixture essentially consisting of titanium powder (Ti), boron carbide (B4C) powder and boron nitride (BN) powder.;COPYRIGHT: (C)2001,JPO
