Production and microstructure of in situ synthesized (Ti,W)C reinforced iron matrix composite
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 .
