  • Internal Porosity Defects in Ductile Cast Iron

    Y. Takemoto, M. Mizumoto and K. Kinno

    International. Journal of Metalcasting ( Springer )    2020.10  [Refereed]

    Academic Journal  Multiple authorship

    The internal porosity defects detected in four castings
    produced in two foundries were carefully observed and
    analyzed by using FE-EPMA, and then, the root cause of
    the defects was investigated. Based on the generally
    authorized theory that the internal porosities might be
    formed at late stage of the solidification, the experimental results are verified. The formation mechanism of dual layer and its characteristic folds or creases on inner surface of defects shown in the experimental results could not be explained by the authorized theory, but the features seem to be possible to explain when the basic films might originate on the surface of the liquid metal and might be entrained in
    turbulent flow. The reductive reaction of carbon and FeO in the solid bifilms formed in the liquid metal is considered to contribute the pore nucleation in ductile iron. Therefore, in addition to the control of the process variables already developed by many researchers, the internal porosity defects in ductile cast irons using resin-bonded sand and cores might be prevented by avoiding the entrainment of carbon and oxide films.
