【Abstract】 The Ti(C,N) based cermets are fabricated by means of powder metallurgy method and its mechanical properties, i. e. hardness, bending strength and fracture toughness are HR a91.2, 1 250 MPa and 13.4 MPa·m 1/2 respectively. TEM examination has shown that there are some orientation relations between the interfaces of ceramics/metals and ceramics/ceramics respectively. The above work reveals the solidification process of metals after liquid sintering.更多还原
