Abstract: In-situ production of (Fe,Cr)7C3 particulate bundles-reinforced iron matrix composites
were prepared by infiltration casting between Cr wires and white cast iron at 1200&C plus
subsequent heat treatment. The composites prepared under different heat treatment time were
characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), macrohardness test
and pin-on-disc wear resistance test. The results show that the composite is mainly consist of
(Fe,Cr)7C3 carbides and γ-Fe. The area of the particulate bundles gradually increases with the
increase of heat treatment time, the microstructure evolved from eutectic to hypoeutectic, and
the morphologies of the reinforcements present chrysanthemum-shaped, granular and
intercrystalline eutectics, respectively. The (Fe,Cr)7C3 particulate bundles reinforced composite
has high macrohardness and excellent wear resistance under dry sliding wear testing conditons.
