摘要：

The present paper deals with the processing method of SiC-(Nb, Ti)((ss))-(Ti,Nb)C-(ss) composites. The electrically conductive phases were formed by in situ reaction: NbC(s) +Ti-(s) -> (Nb, Ti)((s)) + (Ti,Nb)C-(ss) that takes place during the reaction sintering by hot pressing. Prepared composites exhibit good compromise between electrical and mechanical properties and the present approach allows preparing a wide variety of compositions. For example composites containing 80 wt.% SiC and 20 wt.% {(Nb,Ti)((ss))-(Ti,Nb)C-(ss)} have an electrical resistivity 2.6 x 10(-4) Omega m, hardness 21.6 GPa and fracture toughness 6.3 MPa m(1/2), (c) 2005 Elsevier Ltd.
