A powder metallurgy technique combined with in-situ synthesis technique was applied to produce (Ti,W)C particulates reinforced iron matrix composite. The sintered composites were characterized by X-ray diffraction and scanning electron microscopy. (Ti,W)C and α-Fe were detected by X-ray diffraction analysis. The scanning electron micrographs revealed the morphology and distribution of the reinforcements. The results show that the rectangular (Ti,W)C carbides are distributed uniformly in the composite. The (Ti,W)C/Fe matrix interface is found to be free from cracks and deleterious phases. The reasons for the formation of coarse (Ti,W)C particles were also discussed .

The method of infiltration casting plus heat treatment process employing chromium wires and cast iron applied to in-situ synthesized (Fe,Cr)7C3 particulates bundle reinforced iron matrix composites. The phase analysis, microstructure, microhardness and wear-resistance of composite were observed and measured. The results show that it is possible to fabricate (Fe,Cr)7C3 particulates bundle reinforced iron matrix composite produced by this technology, and a special structure which called particulates bundle was fabricated. (Fe,Cr)7C3 particulates bundle were distributed in the forms of granular, lath-shaped and hexagon-shaped in the particulates bundle. The macrohardness of particulates bundle was 52 HRC, and the relative wear resistance of the composites is 2.3—23 times higher than that of the cast iron.

Cast Technique

Vanadium and chromium-carbide particulates reinforced iron matrix surface composite was produced by cast technique and in-situ synthesis technique. The microstructure of the surface composite was studied by scanning electron microscope(SEM) and X-ray diffraction(XRD). The results show that the production of an iron matrix surface composite reinforced by vanadium and chromium-carbide particulates using the process is feasible. Spherical VC particles and strip-chunky Cr7C3 are generated in the surface composite. An excellent metallurgy-bond is observed between the surface composite and the mater-steel.

Iron matrix composite reinforced with VC reinforcements was produced by in situ synthesis technique. The microstructure of the composites was characterized by X-ray diffraction and scanning electron microscopy. The micrographs revealed the morphology and distribution of the reinforcements. The results show that the composite consists of VC carbide as the reinforcing phase and α-Fe as the matrix. The distribution of spherical VC particulates in iron matrix is uniform, and the matrix microstructure of Fe-VC composite is pearlite.
