A Computer-Aided Simulation of the Kinetics of Solidification of the Eutectic Ductile Cast Iron

Abstract

ABSTRACTAn attempt has been made to construct a model of the solidification of the globular eutectic grains which would account for an effect of interblocking the grain growth and would enable calculations starting with the pouring temperature and proceeding until the complete solidification of a casting is obtained. The family of equations proposed in this work enables a simulation of the kinetics of the transformation using a computer and basing only on the knowledge of the materials-designing properties of a foundry mould and the technological parameters of cast iron. The examples of computations given in the paper and the discussion of the results obtained makes it possible to explain the effect of various technological factors on the course of the solidification kinetics of a casting in the cause-effect relation.
