National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Thermodynamic-Kinetic Simulation of Solidification and Phase Transformations in Steels.

PB2001100687

Publication Date	2000
Personal Author	Miettinen, J.
Page Count	68
Abstract	A thermodynamic-kinetic model, IDS (Simulation of Solidification), is presented for the simulation of solidification, phase transformations and solute redistribution in steels. The model has been developed in the Laboratory of Metallurgy, Helsinki University of Technology, since 1984. Depending on the steel composition, the cooling rate and the microstructure dimensions, the model determines the stable phases (liquid, ferrite, austenite and certain binary compounds), and their fractions and compositions during solidification. It also determines the stable phases and their fractions during the austenite decomposition process, at temperatures below 1000 C. In addition, important thermophysical material properties (enthalpy, thermal conductivity, density, etc.) are calculated from liquid state down to room temperature.
