Abstract

IDS is a thermodynamic-kinetic tool for simulation of solidification phenomena and phase transformations in steels, from liquid down to room temperature. IDS calculates important thermophysical material properties (enthalpy, thermal conductivity, density, etc.). The model takes into account the effect of solutes C, Si, Mn, P, S, Cr, Mo, Ni, Cu, Al, N, Nb, Ti, V, Ca, B, O, H, cooling rate and dendrite arm diameter. The model has been developed at Helsinki University of Technology, Finland, since 1984. In addition, IDS is coupled with ChemApp (GTT-Technologies, Germany) to simulate multiphase inclusions during solidification. This paper summarises the features of the model including the future plans. Case calculations of continuous casting, heat treatment and inclusion formation are presented.
