Abstract

Abstract

(Ti, V) C steel bonded carbide was produced by in-situ sintering technology with titanium powder, ferrovanadium powder, carbon powder, ferromolybdenum powder, ferrochromium powder and iron powder.The phases, microstructure and composition of the composites were studied by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrum (EDS).The results show that the sintering temperature and sintering time significantly affect the densification of the alloys.The optimal sintering temperature for TiC, (Ti, V) C steel bonded carbide is 1 420 ℃, 1 400 ℃, respectively.The optimal sintering time is for 1 hour.The main phases of (Ti, V) C alloy are (Ti, V) C、α-Fe、Fe₃C、 (Cr, Fe)₇C₃.Compared with TiC particles, the (Ti, V) C particles present spherulitic morphology.
