Alteration of Graphite Structure by Modified Inmold Process

Abstract

  Alteration process of graphite structure by modified inmold process was investigated. Two reaction chambers were prepared in the sand m old. One reaction chamber was usually for spheroidizing and the other was for inoculating or alloying. As a result, a new hybrid iron material with the graphite alteration morphology from one side having spheroidal, or compacted-vermicular to the other side having flake, was produced by combination with various melt-treating alloys.
