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.
