Calculation of Statistical Values (S′) of Phase Structure Formation Factor (S) and Application to Solidification Theory of Cast Iron

Abstract:

Statistical values (S′) of phase structure formation factor (S) of alloying elements in cast iron are calculated by the calculation method on statistical value of alloy phases electronic structure parameters based on the empirical electron theory of solids and molecules (EET), and the solidification process of cast iron is discussed by S′. According to the effects of phase structure formation factor (that is S′) on the formation process of graphite, cementite and austenite, electronic structure parameters criterion of graphitization behavior of alloying elements is advanced and the results agree well with the practical cases.
