초록
The ultra fine grained TiC-10 vol.% binders (Nicrobraz 30, 150 and LC) hard materials were fabricated successfully by a highfrequency induction heated sintering (HFIHS) using high-energy mechanical ball milled TiC powder. The average grain size of high energy mechanical ball milled TiC powder was approximately 50 nm. TiC-Nicrobraz (30, 150, LC) hard materials with a relative density of up 99% were obtained by HFIHS. The hardness and fracture toughness of the sintered TiC-10 vol% Nicrobraz 30 hard materials produced by HFIHS were 2018.7 kg/mm2 and 8.2 MPa • m1/2, respectively.
