Abstract:

The overall research objective of this project is to determine suitable grain refiners for cast steels. Specific objectives are 1 Identify possible phases to grow delta ferrite and austenite using current nucleation theory, crystallographic data, and thermodynamics. 2 Experimentally verify the effectiveness of possible nucleating compounds. 3 Extend grain refinement theory and solidification knowledge through experimental data. 4 Determine structure property relationships for the examined grain refiners. 5 Formulate processing techniques for using grain refiners in the steel casting industry.
