Analysis on the Impact Fracture of In-situ VCp/Fe Composite
VC reinforced Fe matrix composites have been prepared by in-situ reaction synthesis process. The impact fracture morphology of VCp/Fe composites have been analyzed by optical microscopy and SEM. The results show that the failure of VCp/Fe composites are mainly caused by ferrite cleavage and some pearlite noncontinuous laminar particle cleavage fracture The amount and distribution of VC particles have an important effect on VCp/Fe composites; and matrix can be refined by appropriate increase of carbon content.
