The micro-processes on tensile deformation and fracture of graphite-matrix interface in cast iron with ferrite matrix under SEM have been observed in situ.It was revealed that the graphite in cast iron would not be regarded as a cavity and not formed yet notch stress concentration.A new explanation on the effect of graphite on strength of cast iron was suggested.
