摘要：

A mathematical model for simulating the interdendritic solidification of low-alloyed and stainless steels is presented based on thermodynamic and diffusion calculations made in one volume element in the mushy zone. The method involves the determination of stable phases (ferrite, austenite, liquid, and FeMnS) as well as their fractions and compositions at any temperature during solidification. The model was tested by comparing calculations with experiments, and reasonable agreement was demonstrated. The model also includes a routine for predicting the liquid undercooling caused by solute accumulation of the dendrite tips.
