Elastic properties of ferrite and austenite in low alloy steels versus temperature and alloying

Models for elastic properties, as a function of temperature, are required when simulating various thermo-mechanical processes. A model for hypoeutectoid steels is proposed that accounts for this temperature dependency as well as the influence of alloying. The model consists of separate parts for the ferrite and austenite phases. The latter also includes a specific contribution due to ferromagnetism. The model is calibrated versus iron and evaluated against various steels. Models for elastic properties of iron accounting for alloying effects and changes in Debye and Curie temperatures.
