Abstract:

The overall goals for this project are to elucidate the grain refinement mechanism in cast steels, develop a master grain refining alloy, and determine how heat treatment affects grain refined structures. Specific objectives 1 Determine the cause of intermittent grain refinement in 1010 and 1030 alloys with rare earth additions. 2 Create a master alloy based on rare earth oxides. 3 Extend steel solidification knowledge by understanding how nucleation events occur. 4 Examine how industrial heat treatments affect the structure and properties of grain refined steels. 5 Determine if heat treatments can be modified to improve properties for grain refined steels.
